[57], The unexpectedly low solar activity continued in April 2013. [20], Throughout 2012, NASA posted news releases discrediting the 2012 phenomenon and the so-called Mayan prophecy, delinking them from solar activity and space weather. Six days after, sunspot 1520, the largest active region of Solar Cycle 24 to date, unleashed an X1.4-class flare, peaking at 12:52 PM EDT. If First long-duration flare of Solar Cycle 25 – The K7RA Solar Update. According to the Solar Dynamics Observatory, these CMEs were probably connected to a C3.2-class solar flare that peaked on August 1 at 08:26 UT. The end of the cycle or ‘terminator’ event plays a significant role in the new cycle’s progress, as the shorter the separation between adjoining terminators, the stronger the next cycle will be. The coronal mass ejection starts at 2:36 UTC and ends at 3:56 UTC on August 1, 2010 in this animation on STEREO Ahead images. [69] NASA also reported that these powerful flares heated the Earth's upper atmosphere with the biggest dose of infrared radiation since 2005. An R3-level radio blackout was registered. Forecast for the next 24 hours: This page has information on solar activity for the ham radio DXer. This was followed by an X1.2-class flare at 01:52 UTC on May 15. Friday, … Ham radios operators around the world rejoice — Solar Cycle 25 has officially begun! [17] Solar Cycle 24 has been the subject of various hypotheses and commentary pertaining to its potential effects on Earth. The burst was Earth-directed. Sunspots were observed on only 5 days that month. On October 22 an M8.7-class flare was followed by an X1.6 event. On October 19 there was a major X1.1-class solar flare. On 6 September the largest X-class flare in a decade (X9.3) erupted from active region 2673. [18], The current solar cycle is currently the subject of research, as it is not generating sunspots in the expected manner. "[8] Another group of researchers, including one at NASA, predicted that it "looks like its going to be one of the most intense cycles since record-keeping began almost 400 years ago."[9]. [19], On April 19, 2012, the National Astronomical Observatory of Japan predicted that the Sun's magnetic field would assume a quadrupole configuration. [McIntosh et al. [79], 14 M-class flares were registered this month, the strongest being an M6.0 flare, which erupted on November 13 by AR1613. UPDATED 2015 October 29 0030 UTC .24 hr Summary… Solar activity was at low levels. A filament eruption occurred during the late hours of September 27, resulting in a brief S1 (minor) radiation storm, alerted by NOAA in the early hours of the next day. Even so, it will still produce some good DX opportunities for a few years. A prominent eruption produced a CME off the east limb (left side) of the Sun on April 16, 2012. Should this prove to be the solar minimum, Solar Cycle 24 would uniquely become a short (10 year) and weak cycle. The observed sunspots were 40.8 and the 10.7 cm radio flux value was 108.4, the lowest in ten months. [79] The NOAA categorized the radio blackout associated with the X1.8 event as an R3. Here is the latest news on sunspot activity. Since the charged ions in the ionosphere are negative, a blast of protons from the sun can neutralize the charge and make the ionosphere less refractive. Cycle 23 peak sunspot count was 170 and its F10.7 was about 235. Posted date: March 20, 2020 in: Propagation. An international panel of experts predicted, in June 2009, that Solar Cycle 24 would likely not produce a smoothed sunspot number exceeding 90! [citation needed], A C6.8 flare took place on 9 May 2019, the strongest solar flare to take place since October 2017. This sunspot is the opposite: +/-. [32] Aside from the visual effects of this CME series, scientists warned that electric impulses caused by disruptions in the magnetic field due to the ionized particles may damage infrastructure such as power grids and telephone lines not adequately protected against induced magnetic current. Its location conflicted directly with the expectation from the butterfly diagram. [35] This, however, was only the first wave of solar wind; the third and last was expected for the evening of August 5,[36] but missed Earth entirely. [81], Solar activity decreased significantly this month. It is definitely worth a visit. European observers reported sightings as far south as Denmark near latitude 56° North. According to NOAA, the flare's radiation storm was ranked as S3 (strong), the strongest since May 2005. On August 1–2, 2010, scientists at the Harvard-Smithsonian Center for Astrophysics (CfA) observed a series of four large CMEs emanating from the Earth-facing hemisphere by analyzing images recorded at NASA's Solar Dynamics Observatory.

Sunspot 1402 was rotating onto the far side of the Sun, so the blast site was not facing Earth. Peaking at 01:56 UT on February 15, 2011, sunspot group 1158 produced an X2.2-class solar flare. Sunspots appeared December 24-26, and it looks like a new Solar Cycle 25 spot on January 1. According to Hale’s Law, sunspots switch polarities from one solar cycle to the next. Sunspot 1046 produced an M8.3-class flare on February 12, 2010. The first telescopic observations of the sun started in the 1600’s, with the cyclic nature of sunspot activity being described by Samuel Schwabe in 1843. If you have a question, a comment or a topic you would like me to cover, please do not hesitate to ask here. Overall, the monthly average background 'hard' X-ray level is rising (as seen by the following plot), showing a change from deep solar cycle … On May 14 at 01:17 UTC the same sunspot emitted an X3.2-class flare, the third strongest of the current solar cycle so far. Moreover, the eruptions hurled clouds of plasma in its direction. Discuss band openings, equipment or anything Ham Related. : Big Pic", "Big Sunspot 1520 Releases X1.4 Class Flare", "AR1520's Parting Shot: July 19, 2012 M7.7 Flare", "Magnetic storms online, September 5, 2012", "The Sun Unleashes a Wide, but Benign, CME", "G2 geomagnetic storm (Kp=6) again in progress", "Active Region on the Sun Emits Another Flare", "Major eruption - Active region around east limb produced powerful X1.7 solar flare", "Monthly Solar Flux and Sunspot Averages + Trend Charts", "Space Weather Alerts and Warnings Timeline, 1-15th April 2013". A very similar scenario happened on May 10–11, 2011. Solar Cycle 24 is the most recently completed solar cycle, the 24th since 1755, when extensive recording of solar sunspot activity began. Just in the eve, sunspots 1302 and 1305 had emitted flares almost at the same time; the first event was a C-class and the second one reached a M1.2 category. Also a proud member of an international community of solopreneurs using SoloBuildIt!(SBI! Cycle 24 Activity2. The year 2010 ended up with 21 M-class solar flares. The solar minimum marks the lowest point of sunspot activity and is the official start of a new cycle. The geomagnetic storm reached a G1 level (minor), the same level recorded by the previous M3-class flare. SOLARHAM.com | Solar Cycle 24 | Space Weather and Amateur Radio Website. The most intense flare, produced by sunspot 1385, was an M4.0 event on December 25. It had also been reported that several Earth-orbiting satellites might have been in similar danger. In May 2009 the NOAA Space Weather Prediction Center's Solar Cycle 24 Prediction Panel predicted the cycle to peak at 90 sunspots in May 2013. I must tell you that I find N0NBH's Web site one of the most September 19, … Two days of zero sunspots announcing the low end of solar cycle 24 is near, what does it mean for shortwave radio reception and propagation commission on the transaction, at no extra cost to you. Moderator: Kevin VE3EN. April 5, 2019 – Scientists charged with predicting the Sun’s activity for the next 11-year solar cycle say that it’s likely to be weak, much like the current one. [44][45][46], On August 9 at 08:05 UT, sunspot 1263 produced a massive X6.9-class solar flare, the third X-flare of Solar Cycle 24 and the most powerful so far (as of May 2013). propagation. Likely en route to a Grand Minimum. These rare prognostications are made less than once per decade, during times of ionospheric despair, when the high frequency faithful seek guidance for their future. The related CME was not headed for Earth. Thank you for your contribution. [59] AR2758 continues a trend of increasing Solar Cycle 25 activity. Even so, it will still produce some good DX opportunities for a few years. You will receive a valuable e-book in return for your generosity. Solar Activity is a STRONGLY longitudinal thing and has recurrent repeating patterns. Sunspots did not begin to appear immediately after the last minimum (in 2008) and although they started to reappear in late 2009, they were at significantly lower rates than anticipated. 11 M-class solar flares were observed this month, the largest being an M3.3 flare. On April 5, 2010 the first coronal mass ejection (CME) of Solar Cycle 24 produced by a sunspot (but unrelated to flares; in fact, a single C-class X-ray flux event was registered this month) and causing a true geomagnetic storm was registered. [56] The year 2011 ended up with 111 M-class and 8 X-class solar flares. The flare was classified as an M7.7 flare. The October 24 X3.1-class solar flare was strong enough to trigger a radio blackout. [87], Four solar flares occurred within 5 days from sunspot AR 12192, which is both the largest sunspot of solar cycle 24 and the largest since 1990. HF Radio: Weak or minor degradation of HF radio communication on sunlit side, occasional loss of radio contact. Also a proud member of an international community of. Then, when this region was just crossing the west limb, another X-class flare (SOL2017-09-10, X8.2) produced only the second ground-level particle event of the cycle. These powerful bursts all surged from the just-numbered sunspot AR1748, located on the eastern limb of the Sun and barely rotating around the front of the solar disk. [66] Just one hour after that first flare, nearby sunspot 1430 released a less powerful X1.3-class flare. you make a purchase via a link on this site, I may receive a small commission on the transaction, at no extra cost to you. Infrared radiation from carbon dioxide and nitric oxide, the two most efficient coolants in the thermosphere, re-radiated 95% of that total back into space.[70]. One camp postulated that the Sun retained a long memory (Solar Cycle 24 would be active) while the other asserted that it had a short memory (quiet). The cycle that just ended, Sunspot Cycle 24, peaked with a sunspot number of 116, and the consensus forecast from a panel of experts convened by the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) is predicting that Sunspot Cycle 25 will be similarly weak. [4] Activity was minimal until early 2010. The first wave of plasma impacted the magnetosphere on March 12, causing a G2 (moderate) geomagnetic storm. March 13, 2016 No comments. [76] [75] The CME traveled at over 1500 km (900 miles) per second. The first written evidence of sunspot observations are from around 800BC in China. [74] Other M-class flares registered this month included an M6.9 (July 8, sunspot 1515), an M6.1 (July 5, sunspot 1515), an M6.1 (July 28, sunspot 1532), an M5.6 (July 2, sunspot 1515) and an M5.3 (July 4, sunspot 1515). CME impacts, strong geomagnetic storms and aurorae were registered from September 9 onwards. EDT. The third wave of ionized gas reached Earth on March 15, causing another G2 storm. Thank you! NOAA issued an R3 (strong) radio blackout alert pertaining this prominent x-ray flux event. In principle new-cycle spots should appear at such a latitude, but this region had the correct polarity for Cycle 24. Schatten's predictions become accurate as early as solar minima, 5–6 years before solar max. The connection between both events was established despite the ~400,000 km distance between them.[34].

These waves of protons can be so intense that they may trigger an event called a geomagnetic storm. Sunspot 1402 erupted a long-duration M8.7-class flare, followed by a CME, on January 23, 2012 at 03:59 UTC. KQ6XA 2018-04-28; RE: NOAA: Solar Cycle 24 Status and Solar Cycle 25 Upcoming ; We are currently entering the "minimum" between Solar Cycles 24 and 25. Feed Point Sealant. [77] Climate scientist David Archibald speculates that the Solar Cycle 24/25 minimum could occur as late as March 2021, and that Cycle 25 maximum might not happen until 2027. Solar Cycle 25 by sigurdur Dec 12, 2020 20:18:00 GMT: Amateur (Ham) Radio. The Sun released an M9.0 flare on October 20. [87], The sun emitted a mid-level solar flare, an M7.9-class, peaking at 4:16 a.m. EDT on June 25, 2015. Dikpati's team prediction for Cycle 24 is shown above in pink. No CME associated to this event was reported. These eruptions hurled CMEs, all Earth-oriented. NOAA detected an R3 (strong) radio blackout and an S1 (minor) solar radiation storm. [31] The initial coronal mass ejection of August 1 originated from a sunspot designated Sunspot 1092, which was large enough to be seen without the aid of a solar telescope. The combined CMEs of these bursts arrived at Earth on September 9, provoking a G3 (strong) geomagnetic storm. Solar particles stream down the field lines toward Earth's poles. The ARRL’s Propagation Forecast Bulletin #1 for 2020, dated January 3, reports the following: Sunspots appeared recently, all indicating Solar Cycle 25 due to their polarity, opposite from spots in Solar Cycle 24. [1][2] It began in December 2008 with a smoothed minimum sunspot number of 2.2,[3][failed verification] and ended in December 2019. The current solar cycle, Cycle 24, is declining and predicted to reach solar minimum – the period when the Sun is least active – late in 2019 or 2020. SDO multi-wavelength image of the August 1, 2010 event. [82], 2012 ended up with 129 M-class and 7 X-class solar flares. If you have a question, a comment or a topic you would like me to cover. [11] In May 2012 NASA's expert David Hathaway predicted a peak in Spring of 2013 with about 60 sunspots.[12]. Current Solar Image from SOHO: Current Solar Flux report: SFI: 80 A-index: 3 K-Index: 2 Report last updated: 00:11utc 31 Mar 21 Current Sunspot Count: 13: Highs for Cycle 24 Flux: 237 - 7 Jan 2014 Sunspots: 296 - 17 Apr 2014 : Summary for the past 24 hours: No space weather storms were observed for the past 24 hours. Sunspot 1283 erupted with an M5.3-class solar flare on September 6 at 01:50 UT. causing aurorae to appear on the night of Monday, September 3. [30] According to reports, aurorae would be visible at night toward the poleward horizon in temperate latitudes between 45° to 50°, and near overhead in regions closer to the poles. But, hey! SOHO view of the Jan 23, 2012 M8.7 flare. The first two explosions, X1.9 and M7.1, propelled a pair of closely spaced CMEs. Southern sunspots from old Solar Cycle 24 have a -/+ polarity. Although the flare was not Earth-directed, radiation created waves of ionization in Earth's upper atmosphere, briefly disrupting communications at some VLF and HF radio frequencies. The delayed onset of high latitude spots indicating the start of Solar Cycle 24 led the "active cycle" researchers to revise their predictions downward and the consensus by 2007 was split 5-4 in favor of a smaller cycle. By the next day (yesterday) it had already faded away into nothingness. [57], Active sunspot 1401 erupted an M3.2-class solar flare and a full-halo CME on January 19, 2012. 4 minor solar flares, below M2, were registered in September 2012. This sequence of flares produced waves of ionization in Earth's upper atmosphere, briefly altering the propagation of low-frequency radio signals around Earth. [71] Nevertheless, this month was very quiet in comparison to the previous one, as only two M-class flares were recorded. Solar activity remained extremely low throughout 2009. In the early morning hours of August 4, 2010, aurorae occurred in the northern hemisphere that were visible at latitudes as far south as Michigan and Wisconsin in the United States, and Ontario, Canada near latitude 45° North. This fact was discovered by the THEMIS spacecraft in 2008. In other words, we are told not to expect too much out of solar cycle 24. Here is the latest picture showing sunspot activity! An R3-level radio blackout was reported. recommend without hesitation. Sunspot 1260 produced an M9.3-class solar flare on July 30, 2011. For first time in two years (since December 2010), no X or M-class flares were emitted by the Sun's Earth-facing side (the strongest flare was merely a C4.1). Latest News on Solar Activity. If this solar minimum prediction is correct, it would make Solar Cycle 24 the seventh longest on record at 11.4 years. This officially marked the start of sunspot cycle 24. An S1 (minor) proton storm event was also detected in connection with the May 15 X1.2 flare. The sun's activity provided ham radio operators all over the world with a number of Please contribute [ $0.99 ] - [ $3.99 ] - [ $4.99 ] - [ $5.99 ] by way of thanks. The month ended up with 45 M-class flares and 2 X-class flares, which is the highest number of such flares within the current solar cycle to date. Loudspeakers for Ham Radio – ICQ Podcast Episode 275. Unrelated to the multiple coronal mass ejections, some days after, on August 14, a C4.4-class flare produced the first solar radiation storm of Solar Cycle 24. The related CME impacted the Earth on March 8, causing a G3 (strong) geomagnetic storm. The CMEs were hurled by three M-class flares erupting in active sunspot 1261: M1.4 on August 2, M6.0 on August 3 and M9.3 on August 4. ] first long-duration flare of 19 January 2012, one of the Sun emitted a solar..., peaking as an R3 22 an M8.7-class flare was followed by an flare.
