STA Report comments zum M9 heute Morgen

[Ulrich Rieth]

Comment added at 08:06 UTC on November 8: Region 9687 appears to have been the source of a major impulsive M9.1 flare at 07:04 UTC. A type II radio sweep was recorded as well and a geoeffective CME may have been produced (the absence of LASCO images until Nov. 9 makes it difficult to verify this).

Comment added at 12:41 UTC: The CME which likely was produced by the above major flare could reach Earth on November 10, probably during the latter half of the day and may cause active to major storm geomagnetic conditions.
