Aurora Watch
Good afternoon. Below is an awesome aurora photo sent to us by Dan Ungrue. He captured the shot on February 20th from Alpine Oilfield on Alaska's north slope, 250 miles north of the Arctic Circle. Beautiful and thanks for sharing!

More aurora will be possible in the days ahead when a coronal hole stream is expected to become geoeffective. A minor (G1) geomagnetic storm watch will be in effect for the next 48 hours. Stay tuned to SolarHam.com for the most up to date information.

New Active Region / Prominence Eruption
Good afternoon. Solar activity continues at very low levels, although there is now an increased chance for minor C-Flares and a small chance for an isolated moderate M-Flare. This thanks to the addition of newly numbered region 2638, now in view off the northeast limb. More updates to follow regarding this active region whenever necessary.

Also of interest today, a prominence eruption just behind the northeast limb. The towering stream of plasma was observed by the Solar Dynamics Observatory (SDO) beginning at 16:30 UTC (Feb 20). Because the event was not facing Earth, it should have no impact on our planet.

Stay tuned to SolarHam.com for the most up to date spaceweather news, data and imagery.

Prepared jointly by the U.S. Dept. of Commerce, NOAA,
Space Weather Prediction Center.
UPDATED 2017 February 24 1230 UTC

.24 hr Summary...
Solar activity reached low levels this period.  Region 2638 (N18E15,
Cao/beta), the only region with sunspots, produced isolated low-level
C-class flare activity but continued a minor decay trend.

A filament eruption centered near S12E15 was observed in GONG H-Alpha
imagery beginning at around 24/0020 UTC but no associated CME was
observed in available coronagraph imagery.
  
.Forecast...
Solar activity is expected to be at very low levels with a chance for
C-class flare activity over the next three days (24-26 Feb).
