Here is this week's space weather and geophysical report, issued 2021 Mar 29 0157 UTC.

Highlights of Solar and Geomagnetic Activity 22 - 28 March 2021

Solar activity was at very low levels throughout the highlight period with only B-class flare activity. There was a CME off the NW limb observed in LASCO C2 imagery near 22/0230 UTC. This ejection likely arrived late on 24 Mar and subsequently caused G1 (Minor) storm levels on 25 Mar. No other significant solar activity was observed during the highlight period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 22-26 Mar due to influences from multiple coronal hole high speed streams. Normal to moderate levels were observed on 27-28 Mar.

Geomagnetic field activity reached G1 (Minor) storm levels on 25 Mar due to the likely arrival of the aforementioned CME from 22 Mar. Active levels were observed on 23, 26, and 27 Mar due to influences from recurrent, negative polarity cornal hole high speed streams. Quiet to unsettled levels were observed on 22 and 28 Mar.

Forecast of Solar and Geomagnetic Activity 29 March - 24 April 2021

Solar activity is expected to be very low for the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 10-13 and 17-22 Apr due to influences from recurrent coronal hole high speed stream activity. Normal to moderate levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to be at active to G1 (Minor) storm levels on 29-30 Mar, 08-10 Apr, and 16-17 Apr, all due to recurrent coronal hole high speed stream influences. Quiet to unsettled levels are expected for the remainder of the outlook period.

Space Weather and Ham Radio YouTube Channel News:

I am working on launching a YouTube channel overhaul, that includes series of videos about space weather, radio signal propagation, and more.

Additionally, I am working on improving the educational efforts via the email, Facebook, YouTube, Tumblr, and other activities.

You can help!
