Bülletään

During the past 24 hours, the sun produced an X flare, two M flares and four C flares. Most flares originated from sunspot region Catania 16 (NOAA active region 11875), except for two C flares originating from Catania 18 (NOAA AR 1877) and NOAA AR 1873. The X1.0 flare peaked at 1:41 UT on October 28 and was associated with a Type II burst (estimated shock speed of 700 km/s by Culgoora). In the next 48 hours, M and X flares are likely to occur. LASCO C2 and STEREO COR2 A observed several CMEs on October 27 and 28, among which a halo CME first registered by LASCO C2 at 2:12 UT on October 28 (associated with the X1.0 flare, CME speed estimated at 590 km/s). Another CME first detected in LASCO C2 at 4:48 UT on October 28 was related to an M5 flare. Both CMEs are mainly westward oriented and could deliver a glancing blow in the second half of October 30. Solar wind speed measured by ACE is currently around 300 km/s, while the interplanetary magnetic field (IMF) reached a maximum of 7 nT during the past 24 hours. Current geomagnetic activity is at quiet levels (local K at Dourbes between 0 and 3; NOAA Kp between 0 and 1). Active to minor storm conditions are possible within the next 24 hours, due to the expected arrival of the CMEs of October 25. Active geomagnetic levels are possible in the second half of October 29 and October 30, due to a possible glancing blow by the partial halo CME of October 26 and a possible glancing blow related the two partial halo CMEs of October 28.
