公告

There are only two sunspot groups currently visible on the solar disk, and no C flares occurred during the past 24 hours. In the next 48 hours, eruptive conditions (C flaring) are possible, especially from beta region NOAA AR 2187. A bright CME was first seen in the SOHO LASCO C2 field of view at 00:00 UT on October 13. It had an angular width of about 90 degrees and is probably associated with an eruption in a backside region close to the west limb. This CME is not expected to be geoeffective. Over the last 24 hours, solar wind speed observed by ACE was low and fluctuated between about 310 and 340 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) first varied between 4 and 8.5 nT, and jumped from 5.5 to 9 nT around 5:45 UT on October 13, possibly due to an unidentified ICME structure. Over the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 1 and 3; NOAA Kp between 1 and 2). Quiet geomagnetic levels (K Dourbes < 4) are expected on October 13, 14 and 15, with a slight chance for active levels (K Dourbes = 4) in the early hours of October 14 in case the glancing blow of the CME from October 10 encounters the Earth.
