The wave of high energy electromagnetic rays, reaching Earth in minutes, caused an R3 (strong) radio blackout over China, India and Australia, according to NOAA. 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. commission on the transaction, at no extra cost to you. Solar Activity is a STRONGLY longitudinal thing and has recurrent repeating patterns. Portable Solar Power, Samlex Foldable Solar Panel, Off-Grid Emergency Electricity. The filament eruption was connected to a C3.7 flare which occurred in the vicinity of sunspot 1577. The observed monthly sunspots exceeded 10 only in December. It began in December 2008 with a smoothed minimum sunspot number of 2.2, and ended in December 2019. Peaking at 01:56 UT on February 15, 2011, sunspot group 1158 produced an X2.2-class solar flare. If the solar eruption is very intense, the radiation that it releases can interfere with our radio communications here on Earth. The first wave of plasma impacted the magnetosphere on March 12, causing a G2 (moderate) geomagnetic storm. 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. The geomagnetic storm reached a G4 (severe) level, enough to create power outages. A solar wind stream flowing from these zones is predicted to reach Earth beginning late on March 27th and into the 28th. An R3-level (strong) radio blackout alert was issued. Larger than the planet Jupiter, the AR 12192 sunspot was visible during a partial solar eclipse seen in North America. 9 M-class flares were unleashed by active regions 1045 and 1046 this month. This unexpected stage prompted some scientists to propose a "double-peaked" solar maximum, which then occurred. AR2744 is therefore a member of Solar Cycle 25. [75] A G2 (moderate) geomagnetic storm was registered on September 3 and September 5. This so-called "monster" sunspot complex, the largest active region of the cycle to date, was about the size of Jupiter, or eleven times the diameter of Earth.[72]. [57], Active sunspot 1401 erupted an M3.2-class solar flare and a full-halo CME on January 19, 2012. NOAA detected an R3 (strong) radio blackout and an S1 (minor) solar radiation storm. The previous solar cycle prediction panel’s forecast for solar cycle 24 called for a maximum average sunspot number of 90 to occur in May, 2013. Dubbed the Valentine's Day solar event by the scientific community, it was the first Solar Cycle 24 flare reaching X class level. A very similar scenario happened on May 10–11, 2011. 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. After countless dire predictions for the upcoming cycle indicating similar or even poorer activity levels than the disappointing Cycle 24, the new paper suggests just the opposite! Schatten's predictions become accurate as early as solar minima, 5–6 years before solar max. [55], Solar activity increased again in late December, with the Sun unleashing eight M-flares. recommend without hesitation. This sequence of flares produced waves of ionization in Earth's upper atmosphere, briefly altering the propagation of low-frequency radio signals around Earth. In total, the Sun produced four X flares and 31 M flares in September 2011, one of the most active months of Solar Cycle 24 so far. Sunspot 1260 produced an M9.3-class solar flare on July 30, 2011. An R2 (moderate) blackout radio alert was issued. Hathaway's Cycle 24 and 25 predictions are shown in red. The origin of this blast was sunspot 1092. [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. [1][2] It began in December 2008 with a smoothed minimum sunspot number of 2.2,[3][failed verification] and ended in December 2019. AR2758 continues a trend of increasing Solar Cycle 25 activity. [71] The CME was not aimed toward Earth. On March 9, active region 1166 erupted in an X1.5 flare. A G4 (severe) geomagnetic storm was reported on September 26.[51][52]. According to NASA, the intensity of geomagnetic storms during Solar Cycle 24 may be elevated in some areas where the Earth's magnetic field is weaker than expected. No CME associated to this event was reported. NOAA named the spot AR10981, or sunspot 981 for short. Waves of ionization in the upper atmosphere created an R3 (strong) radio blackout. Solar Cycle 24.com Solar Cycle 24 / VHF Aurora / amateur radio website. An R3-level radio blackout was registered. This was followed by an X1.2-class flare at 01:52 UTC on May 15. The observed sunspots were 40.8 and the 10.7 cm radio flux value was 108.4, the lowest in ten months. These waves of protons can be so intense that they may trigger an event called a geomagnetic storm. James KJ6WU, The QCX+, by QRP Labs, is a solid, well-designed SDR QRP transceiver in bands 17 to 80m. The geomagnetic storm reached a G2 (moderate) level on the NOAA scale. Sunspots were observed on only 5 days that month. However, these numbers are well below those of Cycle 23 at its peak. The flare was classified as an M7.7 flare. Sunspot 1007 produced the first solar flare above the B-class on November 2, 2008. Sunspots appeared December 24-26, and it looks like a new Solar Cycle 25 spot on January 1. This sunspot is the opposite: +/-. [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. [19], On April 19, 2012, the National Astronomical Observatory of Japan predicted that the Sun's magnetic field would assume a quadrupole configuration. [79], 14 M-class flares were registered this month, the strongest being an M6.0 flare, which erupted on November 13 by AR1613. good to excellent signal propagation conditions. 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. Latest News on Solar Activity. The proton storm event was minor, rating at S1, and was easily absorbed by the ionosphere. [60] The very fast-moving CME arrived at the Earth on January 24 at approximately 15:00 UTC. Even so, it will still produce some good DX opportunities for a few years. Sunspot 1046 produced an M8.3-class flare on February 12, 2010. Prepared jointly by the U.S. Dept. [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. [53], On November 3, 2011, active region 1339, one of the largest sunspots in years - 40,000 km wide and at least twice that in length - unleashed an X1.9-class solar flare.
