Uptick in solar activity, SDO HMI/AIA data distribution center under emergency repairs

Solar activity is picking up again. After M3.5 on December 19 at 23:19 UTC and M1.6 on December 20 at 11:57 UTC Sun unleashed more M-class flares today and it looks like it's going to continue. Today, Region 1928 (S18W55, Ekc/beta-gamma) produced M1.9 at

Impulsive solar flare measuring M3.5 erupted from eastern limb

Impulsive solar flare measuring M3.5 erupted on December 19 at 23:19 UTC. The source of the event was centered around new active region in close proximity to AR 1931 located on eastern limb. This region is not yet in position to cause Earth directed

Moderate M1.2 solar flare erupted around AR 1909

Moderate solar flare measuring M1.2 erupted today from around AR 1909. The event started at 07:17, peaked at 07:29 and ended at 07:49 UTC. Region 1909 (S17W50, Dso/beta) is decreasing in size but maintains some magnetic complexity. A 10 cm Radio Burst

Second moderate solar flare around western limb - M1.0

After an impulsive M1.1 solar flare at 02:23 UTC today, a second M-class solar flare erupted from AR 1904 located around the west limb. The latest event peaked at 12:27 UTC as M1.0 solar flare. No Earth directed CMEs were observed. Image credits: NOAA SWPC/NASA

Impulsive M1.1 flare erupted around western limb

An impulsive M1.1 solar flare was detected around departing Sunspot 1899 at 02:32 UTC on November 23, 2013. The source was actually a newly numbered Region 1904 (N12W60, Dai/beta-gamma). This region appeared to have enough of a separation in SDO HMI/Magnetogram imagery

M1.2 solar flare erupted from Sunspot 1893 behind the western limb

A moderate M1.2 solar flare was detected around sunspot 1893 at 11:11 UTC on November 21, 2013. This active region is now located behind the west limb, so any subsequent coronal mass ejections (CMEs) would be too far west to impact Earth. This same region is

Solar flare reaching X1.0 erupted from southwest limb

Solar flare peaking as X1.04 erupted from Sun's southwest limb at 10:26 UTC on November 19, 2013. This event was observed around 'beta-delta' classified AR 1893.  A Type II Radio Emission was registered at 10:24

Solar activity at moderate levels today - two M-class solar flares

In last 24 hours solar activity was at moderate levels due to two M1 flares at 04:53 UTC and 07:49 UTC from Region 1900. No Earth-directed coronal mass ejections were observed.  There are currently 10 numbered sunspot regions on the

New AR1897 unleashed moderate M1.4 solar flare

Active Region 1897 unleashed moderate M1.4 solar flare on November 13, 2013 at 15:20 UTC. This region has 'Beta-Gamma' magnetic configuration and is capable of producing strong eruptions on the Sun. It is still rotating into geoeffective position

Rising threat of solar eruptions as new active regions rotate into Earth view

Four new active regions were numbered in the past two days - 1895, 1896, 1897 and old Sunspot 1875 which was just numbered as 1899. Sunspot 1897 already produced a few C-class flares and grew in size and complexity. This active region could produce strong flares in

Moderate M2.4 solar flare erupted from new region on eastern limb

Active Region 1897 emerged yesterday on eastern limb of the Sun and erupted today with long duration M2.4 solar flare at 11:18 UTC. No Earth-directed CME was observed but this region already produced multiple C-class flares today.  The

Major X1.1 solar flare erupted from Earth facing AR 1890

Active Region 1890, located almost at the center of the disk, erupted with impulsive X1.1 solar flare at 05:14 UTC on November 10, 2013. A very bright Coronal Mass Ejection (CME) has been observed and the bulk mass seems to be heading well south of the

Sunspot 1890 produced powerful X3.3 and three M-class solar flares

New active region 1890 produced yet another strong impulsive flare. Powerful X3.3 solar flare erupted at 22:12 UTC on November 5, 2013. This sunspot group already produced 2 M-class and dozens of C-class solar flares in the past two days. A Coronal Mass

New active region 1890 produced impulsive M2.5 solar flare

After increased solar activity in second half of October, solar activity was down to minor and moderate levels for last couple of days. On November 3, 2013 new sunspot group AR 1890 emerged off the southeastern limb and produced a C9.9 flare at 16:28 UTC.  When

More flaring activity from central region of the Sun

Moderate M1.6 solar flare erupted from Sunspot 1884 at 22:21 on November 2, 2013. Active Region 1884 is now located at the center of the visible solar disk and any strong eruptions can generate Earth-directed plasma cloud. Few hours later, at 05:22 UTC on
