Welcome to SolarHam.com   All of your solar and aurora needs in one place!
Good morning. Here is an updated look at the visible solar disk on Sunday. Solar activity during the past 24 hours continued at low levels. Region 2303 nearing the west limb showed signs of growth while it produced much of the detected low level C-Class flares. It will soon be out of direct Earth view. In the southern hemisphere, region 2305 continued to decay and is a decreasing threat for moderate M-Flares. New regions 2315 and 2316 are both stable this morning. A number of coronal mass ejections were observed during the past 24 hours, however each appear to have originated from either the farside or limb locations.
Elevated geomagnetic activity will remain possible during the next 72 hours due to an enhanced solar wind stream. Sky watchers at high latitudes should remain alert for visual aurora

Prominence Eruption and CME
A large prominence located off the northeast limb erupted on Friday morning. A coronal mass ejection (CME) was produced, however due to the location near the limb, it is likely directed away from Earth. No major impacts are to be expected. Still a nice looking event! A video is located below.

.24 hr Summary...
Solar activity was at low levels with C-flare activity from both Regions
2303 (N18, L=065) and 2305 (S10W43, Dho/beta). The largest flare of the
period was a C4 at 30/0152 from Region 2303 just beyond the NW limb.
Slight decay was observed in the leading spots of Region 2315 (S20W36,
Dro/beta) and the trailing spots in Region 2305. No Earth-directed
coronal mass ejections were observed.
Solar activity is likely to be at low levels with a slight chance for an
isolated M-class (R1-R2, Minor-Moderate) flare for days one and two
(30-31 Mar). An increase in activity is expected by day three (01 Apr)
due to the return of old Regions 2302 (N12, L=189) and 2297 (S17,
L=196). Solar activity is expected to increase to low levels with a
chance for M-class flares by day three.
