This time it is not Catania sunspot group 065, but sunspot group 070 (NOAA 10486) that is responsible for all the trouble. This group rotated over the east limb on October 23.

The SIDC has sent an alert message on October 19 at 18:07 UTC:
An X1.2 flare took place a few minutes ago (Start: 16:27 , Peak: 16:50 , End: 17:20UTC) in active region Catania 065 - NOAA 10484 (position N06E61). This event will affect radio propagation and may be followed by other M-class flares, and maybe another X-class flare in the next few hours and days.

Above is a picture from the LASCO C2 coronagraph showing a full halo coronal mass ejection (CME) surrounding the solar disk. This CME left the Sun on July 16 around 16UT. Its origin and direction were puzzling. It was not certain whether the CME was directed straight towards Earth or was directed away from us.

Although solar activity is generally low these days, beautiful Coronal Mass Ejections can still be seen frequently, such as the one depicted here, which happened on Jul 23. Enjoy the movie from the C2 field of view, made by the LASCO instrument on board the SOHO spacecraft.

Watch the Sun blast off a streamer type plasma cloud in the corona by shooting a fast CME through it.
Images and movies were made on 6-7 May 2001 by the LASCO instrument on board the SOHO spacecraft.
