Welcome to SolarHam.com   All of your solar and aurora needs in one place!
Good evening. At approximately 22:00 UTC Thursday evening (May 21), a large eruption originating from behind the northeast limb was responsible for a bright, fast moving coronal mass ejection (CME). Attached video below courtesy of the Solar Dynamics Observatory (SDO) using the 304 angstroms channel, along with coronagraph imagery courtesy of LASCO C2 and C3, captures the noteworthy solar event. Because this was a non Earth facing eruption, there should be little to no impact on our planet. Meanwhile, on the Earth facing side of the sun, solar activity remains stuck at very low to low levels. Stay tuned to SolarHam.com for the latest spaceweather data and imagery.

Good morning folks. Quiet times on the sun the past 24 hours with no noteworthy solar flares to report. Activity could remain at very low to low levels (C-Flares) in the short term. A new sunspot is forming in the northeast quadrant and will be monitored. No Earth directed coronal mass ejections were detected during the past day. Geomagnetic activity is also expected to be at quieter levels during the next 48 hours. Below is an updated image of the visible disk courtesy of the Solar Dynamics Observatory.

.24 hr Summary...
Solar activity was at very low levels. Two new regions emerged during
the period, Region 2352 (N05E16, Dro/beta) and Region 2353 (N08E02,
Cao/beta). All other regions were either stable or in decay.
A nearly 10 degree long, linear filament located at approximately N16E02
became active and slowly dissipated between 22/0300-0600 UTC. Analysis
of SDO/AIA imagery indicated the filament was likely reabsorbed.
At about 21/2204 UTC an eruptive event was noted from behind the NE limb
in SDO/AIA 304 imagery. Subsequent SOHO/LASCO C2 coronagraph imagery
revealed a partial halo coronal mass ejection (CME) first seen at
21/2224 UTC associated with this activity. Analysis of all available
imagery did not reveal any front side signatures related to this event
and it is likely this was a backside event and not Earth-directed.
Solar activity is expected to be very low with a chance for C-class
activity over the next three days (22-24 May).
