Geomagnetic Storm Watch
A solar wind stream flowing past Earth remains above 700 km/s. A brief period of minor geomagnetic storming (Kp=5) was observed early this morning at high latitudes. Additional flareups of minor storming will be possible today, particularly if the Bz/IMF component decides to tip south for an extended period of time. Stay tuned for the latest information.
UPDATE: A solar wind stream flowing from a geoeffective coronal hole remains elevated near 700 km/s heading into Friday evening and the Bz/IMF component remains fairly stable. Only minor geomagnetic disturbances (Kp=4) have been detected today so far. There will remain a chance for isolated storm conditions (Kp=5) at high latitudes tonight. Be on the lookout for visible aurora should geomagnetic conditions allow.
Solar activity is currently low with only minor B-Class activity detected within the past 12 hours and an impulsive C1.3 flare moments ago at 12:47 UTC around Sunspot 1818. Both regions 1817 and 1818 have a Beta-Gamma-Delta magnetic configuration. There will remain a chance for C-Class flares and perhaps an isolated M-Class event. A small eruption registering as a C2.9 solar flare Thursday evening to the west of 1817 generated a faint Coronal Mass Ejection (CME) now visible in the updated Lasco C2 imagery. It does not appears to be Earth directed.
UPDATE: 1817 again appears to be weakening, but 1818 retains a delta configuration and is currently producing impulsive C-Class solar flares.
