November 08, 2013 - SUN - Solar activity is again at high levels with a major X1.1 solar flare detected around sunspot 1890 at 04:26 UTC.
X1.1 SOLAR FLARE: Big sunspot AR1890 is crackling with strong flares. The latest, registered X1 on the Richter Scale of Flares. This sunspot has a signature: It tends to produce very brief flares. The X1-flare was no exception as it lasted barely a minute. Brevity mitigates Earth-effects, so this intense flare was not strongly geoeffective--at least, not at first.
The event was associated with a 10cm Radio Burst (TenFlare) measuring 1000 sfu, along with Type II and IV sweep frequency events. A CME became visible in LASCO C3 imagery, following the explosion, and appears that a majority of the plasma was directed to the south.
There may be a small Earth directed component and the latest CME tracking model released by the Goddard Space Flight Center is showing a glancing blow impact possible by November 11th, possibly sparking polar geomagnetic storms.
WATCH: Major X-Class Solar Flare - November 8, 2013.
It should also be noted that sunspot 1891 generated a moderate M2.3 flare at 09:28 UTC this morning.
More eruptions are in the offing. NOAA forecasters estimate a 60% chance of M-class solar flares and a 20% chance of X-flares on Nov. 8th.
SUNSPOTS: Below is an updated look at the visible solar disk on Friday. Sunspot 1890 remains the largest visible Earth facing region and retains a delta configuration within the trailing section of the group. The active region will be in a near perfect geoeffective position over the next 3 days and is likely that future eruptions would be at least partially Earth directed.
Sunspot 1891 continues to possess a weak delta configuration and produced a moderate M2.3 solar flare at 09:28 UTC Friday morning. A new sunspot rotated into view off the east limb and should be numbered 1893 today. It appears to be stable with a simple magnetic layout. There will remain a chance for another isolated moderate to strong solar flare within the next 24 hours with 1890 being the most likely source.
CORONAL HOLE: Solar wind flowing from the indicated coronal hole could reach Earth on Nov. 10-11.
