公告

Flaring activity has slightly increased during the past 24 hours. Two C-class flares were produced by Catania sunspot group 33 (NOAA AR 2047). The C4.4 flare, peaking at 9:40 UT, on 2 May was accompanied by a coronal dimming located at the south of the region. This hints at the occurrence of CME oriented to the south, but no coronagraphic imagery is available yet to analysis this. Catania sunspot groups 33 and 34 (NOAA AR 2047 and 2049 resp) showed some growth and sunspot group 33 now also has a beta-gamma magnetic configuration of its photospheric field. Two new sunspot groups emerged with Catania numbers 36 and 37. More C-class flares can be expected, especially from sunspot groups 33 and 34. There is moderate chance (around 40%) for M-class flares. We are currently under the influence of a slow solar wind. The solar wind speed decreased 400 to 340 km/s. The magnitude of the interplanetary magnetic field went from 8 to 2 nT. Geomagnetic conditions were quiet to unsettled and are expected to remain as such for the next 48 hours. The slow CME of UT night of 29-30 April could arrive at around 5 May 0:00 UT, possibly leading to a limited time of active conditions.
