Sunspot Returns

Below is a look at old region 2817, now turning back into view from behind the northeast limb. It will be reassigned AR 2822 today and is likely a threat for an isolated minor C-Flare. Image by SDO/HMI.

2817 Set to Return
May 6, 2021 @ 09:30 UTC
Region 2817 from the previous rotation is set to return into view during the next 24-48 hours. Imagery courtesy of STEREO Ahead suggests that it may still be somewhat active. At least a small increase in solar activity may be possible. Stay tuned to find out!

Farsided Activity
May 2, 2021 @ 14:25 UTC
Old region 2817 is currently transiting the farside of the Sun and it appears to be active. An eruption was captured today (Sunday) by the STEREO Ahead spacecraft and a coronal mass ejection (CME) is now becoming visible. Because this took place on the farside of the Sun, it will not be directed towards Earth. The region is due to turn back into view starting in about 5 days.

Solar Update / Aurora Watch
May 1, 2021 @ 14:00 UTC
Welcome to the month of May.

Solar activity remains at very low levels. Decaying AR 2818, along with plage region 2820 are about to rotate out of view and behind the southwest limb. Elsewhere, a potential active region is still about 2 days away from turning into view from behind the southeast limb. We will know more in a few days. For now solar flare activity is expected to remain at quiet levels.

A small but sudden increase in solar wind speed was detected within the past hour. This could possibly be an expected weak CME passage following a filament eruption on April 26th. A reminder that enhanced geomagnetic activity is predicted for the next 48 hours due to the possible CME passage, along with an expected coronal hole solar wind stream.

Stay tuned to for the most up to date information.
