Update
MAJOR SOLAR FLARE ALERT:
A major solar flare reaching X1.7 peaked at 08:01 UTC early Friday morning.
The flare was centered around Sunspot 1882 and produced a bright CME.
Added 10/25/2013 @ 09:20 UTC
ANOTHER X-FLARE (X2.1)
Sunspot 1882 now in view off the southeast limb produced the second X-Class flare of the day. The latest major event at 15:03 UTC peaked at X2.1. A strong radio blackout was observed on the sunlit side of Earth. While listening to the 10 meter (28mhz) amateur radio band, signals went from very strong to almost nothing in a matter of minutes. Signals did start to recover after about 15 minutes. A coronal mass ejection (CME) is likely. More updates to follow.
