Solar Update: Chance of Geomagnetic Storms

Blogger note: Some believe that increased Solar activity results in increased tectonic movement on Earth. As you know, there has been a notable uptick in earthquake activity in the last week or so... in California, Yellowstone and South America. People in these regions should stay alert!

Beautiful Eruption
Solar activity continues at moderate levels thanks to an M1.4 solar flare this morning observed around departing sunspot 2014 at 08:07 UTC. A beautiful eruption of plasma was captured during the event by the Solar Dynamics Observatory (SDO) as seen in the image below. Any associated coronal mass ejection (CME) would likely be directed away from Earth due to the location near the west limb.

Geomagnetic Storm Watch Issued
A minor geomagnetic storm watch has been issued by the NOAA space weather prediction center (SWPC). A couple of coronal mass ejections stemming from eruptions around 2017 may deliver glancing blows to our geomagnetic field by late on April 1st. Sky watchers should remain alert during the next several days.
WATCH: Geomagnetic Storm Category G1 Predicted
Highest Storm Level Predicted by Day:
Mar 31: None (Below G1) Apr 01: None (Below G1) Apr 02: G1 (Minor)
Potential Impacts: Area of impact primarily poleward of 60 degrees Geomagnetic Latitude.
Induced Currents - Weak power grid fluctuations can occur.
Spacecraft - Minor impact on satellite operations possible.
Aurora - Aurora may be visible at high latitudes, i.e., northern tier of the U.S. such as northern Michigan and Maine.

Solar Update
Good morning and welcome to the final day of March. Below is an updated look at the visible solar disk on Monday. Solar activity was moderate during the past 24 hours with a pair of M-Class solar flares. The first event, an M2.1 flare around sunspot 2017 at 11:55 UTC (03/30), generated a non Earth directed coronal mass ejection (CME). The second event, associated with a Type IV radio emission, was an M1.4 eruption around departing sunspot 2014 at 08:07 UTC (03/31). Updated imagery by STEREO Ahead COR2 indicates a possible CME that is likely directed to the west and away from Earth. All other visible regions, including newly numbered regions 2026 and 2027 are currently stable. There will remain a chance for an isolated M-Class flare event within the next 24 hours.
