公告

Nine sunspot groups are reported on the Sun today. Four of them have beta-gamma configuration of the photospheric magnetic field: Catania numbers 23, 24, 25, and 26 (NOAA ARs 2034, 2035, 2036, and 2037, respectively). These four groups produced numerous C-class flares during the past 36 hours. None of the flares was associated with a CME. The strongest flare of today is the C5.2 flare peaking at 08:44 UT in the Catania sunspot group 24 (NOAA AR 2035). The solar soft X-ray background flux is currently around the C1 level. We expect further flaring activity on the C-level from these four sunspot groups, with a good chance for an M-class event. The Earth is currently inside a slow (around 320 km/s) solar wind flow with weak to average (3-4 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.
