Solar Update

The source of a number of farsided eruptions over the past week will begin to turn into view during the next 24-48 hours. This could possibly be the return of old region 2835 from the previous rotation. It remains to be seen just how much gas this likely spotted region has left in the tank.

Farsided CME Activity Continues

Another day, another large CME off the farside of the Sun. The source is likely the same region as most of the others from previous days. Imagery below courtesy of LASCO C2.

Farsided Activity
July 16, 2021 @ 13:00 UTC
Good morning. Solar activity reached low levels during the past 24 hours with a number of very minor B-Flares and low level C-Flares detected around AR 2843, now approaching the SW limb. Earth facing solar activity should remain at low levels in the short term.

The real action is taking place on the farside of the Sun with a number of large scale coronal mass ejections observed in coronagraph imagery. One such event took place during the very early hours on Friday (July 16). The source region will be coming into view of the STEREO Ahead spacecraft during the next few days and will turn into Earth view next week. Perhaps something to look forward to.

Solar Update
July 9, 2021 @ 13:55 UTC
Good morning. Solar activity reached low levels today thanks to a pair of C-Flares (C6.0 and C7.0) observed around AR 2840, now located behind the west limb. It is possible they could have been somewhat larger than actually detected because the region is no longer directly in view of the Earth facing GOES-16 satellite. A Type II Radio Emission with a velocity of 745 km/s was associated with the C7 flare at 10:50 UTC. Any possible CME will be directed away from Earth.

The visible disk is now for the most part spotless, with the exception of a possible new active region developing in the southeast quadrant today. Solar activity should remain at low levels in the short term.

X-Flare!
July 3, 2021 @ 16:05 UTC
Hello again folks. I just returned back from a trip to the zoo with my 6 year old daughter and luckily for me, nothing much of interest occurred on the Sun.

Okay well, that is not entirely true. A new spotted region assigned AR 2838 formed rapidly and produced an X1.5 solar flare at 14:29 UTC (Jul 3). This is now the largest solar flare of Cycle 25, at least in terms of peak X-Ray flux. The region also produced an impulsive M2.7 @ 07:17 UTC (Jul 3). Because AR 2838 is already approaching the west limb, any associated CME activity would likely be directed away from Earth. Elsewhere, large AR 2835 located in the SW quadrant remained mostly stable with only very small B-Class flares detected. There will remain a chance for at least another moderate M-Flare during the next 24 hours.

Big Sunspot
July 1, 2021 @ 23:45 UTC
Large sunspot group 2835 is currently facing Earth and is capable of producing at least minor C-Class solar flares. According to NOAA/SWPC, there is also a lower 15% chance for an isolated moderate M-Flare and 5% chance for a strong X-Flare. This region should be monitored closely during the next 24 hours.
