Space weather highlights for May 07 - May 13, 2012: 55 C-class and 6 M-class flares

Solar activity ranged from low to moderate levels. Region 1476 (N10, L=180, class/area=Fkc/1050 on 09 May) was responsible for almost all x-ray flare activity during the week. It produced a total of 55 C-class flares, 6 M-class flares, and 69 optical

Huge sunspot AR1476 is crackling with M-class solar flares and harbors energy for X-class solar flare

Earth is entering the line of fire as the huge sunspot 1476 rotates across the face of the sun into geoeffective position. Sunspot 1476 is crackling with M-class solar flares and its 'beta-gamma-delta' magnetic field harbors energy for X-class flares. NOAA/SWPC

Solar activity update for May 10, 2012 - M5.7, M1.7

A strong solar flare reaching M5.7 was detected around Sunspot 1476 and peaked at 04:18 UTC on Thursday, May 10, 2012. This event generated a 10cm Radio Burst.TenFlare - a 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the

Solar flare reaching M1.4 and two weak Earth-directed CMEs detected around Sunspot 1476

Solar activity has been at moderate levels for the past 24 hours. Region 1476 (N11E35) is the most complex region on the visible disk, has grown to become a Fkc/beta-gamma-delta configuration, and has an area of approximately 940 Millionths. It also produced the

Sunspot 1476 is crackling with solar flares, soon in geoeffective position

Sunspot 1476  is crackling with impulsive solar flares. Multiple mid level C-Class flares have been detected along with an impulsive M1.3 solar flare at 17:47 UTC. Solar activity is now at moderate levels. New and active Sunspot 1476 has produced three low-level

Sunspot 1476 unleashed a pair of M-Class flares in last 24 hours

Solar activity is now at moderate levels and is increasing. New and active Sunspot 1476 rotated into view off the northeast limb and has so far produced a pair of M-Class flares within the past 24 hours. There will continue to be a chance for another moderate solar

Farside blast, Southeast limb prominence, CME, Geomagnetic storming

For more than a week, solar activity has been low. Today, around 0600 UT, an active region on the farside of the sun broke the calm with a powerful eruption. NASA's Solar Dynamics Observatory recorded a massive cloud of plasma flying over the southwestern

A mild (Kp=5) geomagnetic storm is underway

This is the third day in a row that geomagnetic storms have circled the poles. A mild (Kp=5) geomagnetic storm is underway. It looks like it subsiding now. High-latitude sky watchers should be alert for auroras. The source of this activity is a high-speed solar wind

Subsided geomagnetic storm, new incoming CMEs

Sunspot AR1465 has developed a 'beta-gamma-delta' magnetic field that harbors energy for X-class solar flares. Because of the sunspot's location near the middle of the solar disk, any eruptions will likely be Earth-directed.Earth's magnetic field is quieting after

Unusual magnetic changes in the Sun - The north pole of the Sun had started flipping about a year earlier than expected

While scientists had predicted that the next flip would begin from May 2013, the solar observation satellite Hinode found that the north pole of the sun had started flipping about a year earlier than expected. There was no noticeable change in the south pole.The
