Bülletään

Solar activity was moderate during the past 24 hours, with a M1.0 flare spotted in NOAA AR 1900 on Nov. 17, 0510 UT peak time. A C4.9 flare occurred in NOAA AR 1893, on Nov. 17, 0801 UT (peak time). It was accompanied by a CME observed by the STEREO COR2 coronagraphs. Based on these observations (LASCO data are not yet available for this event) it looks like the bulk of the CME will miss the Earth. A C8.6 flare occurred on the East limb (N15) on Nov. 17, 0621 UT (peak time), but further information is needed to assess the risk of future flares. We expect active conditions (M flares possible) to prevail for the next 48 hours, with a higher risk for NOAA ARs 1900, 1897, and 1893. Geomagnetic conditions are expected to be mostly quiet for the next 48 hours. Current ACE observations show that the Earth is still within the moderately fast solar wind stream linked to a coronal hole, but the interplanetary magnetic field is now back to very quiet and steady levels.
