Sun activity for March 28: Another M-flare

The sun produced another M-flare on March 28, 2022. At 11:30 UTC, a solar flare peaked at M4.1. The M4 eruption produced an R1 level shortwave radio blackout over Africa. A burst of radio waves indicating a possible fast CME was detected. There is also a sudden increase in solar protons. Stay tuned for updates on how this will affect earth.

A CME is due to arrive on March 28, 2022. And a low level geomagnetic storm – with auroras at high latitudes – is possible. NASA said the CME will impact Earth late on March 27, 2022, or early on March 28. Activity at Earth is expected to be minor.

The March 28, 2022, CME is from a March 25 solar flare, which also caused a shortwave radio blackout over southeast Asia.

The large active region AR2976 is rotating away from the limb, getting better positioned for imaging.” Thank you, Michael!

I try to view them yearly, whether it is Iceland, Finland, Canada or Alaska. I shot this at an ISO of 2000 at 12mm, F2.8 @ 6 seconds.” Thank you, Joanne!

Bottom line: Sun activity for the week of March 28, 2022. A CME is due to arrive today. A low level geomagnetic storm – with auroras at high latitudes – is possible.
