公告

There are currently 6 sunspot groups visible on the solar disk, all having simple magnetic configurations. NOAA 2065 produced the strongest flare from just behind the west limb. This C4 flare peaked on 27 May at 14:15UT and was associated to a jetlike CME. It had a speed of nearly 300 km/s, but was not directed to Earth. A new sunspot region developed southeast of NOAA 2073 early on 28 May. There remains a chance on a C-class flare. Solar wind speed gradually increased from 300 to 350 km/s. It is currently stable at 340 km/s, with Bz varying between +6 and -5 nT. The geomagnetic field was quiet. A small coronal hole that passed the central meridian on 25-26 May could influence the geomagnetic field starting late on 29 May. Geomagnetic conditions are expected to be quiet, though locally a brief active episode on 29-30 May is not excluded.
