公告

Only 5 low-level C-class flares were recorded over the last 24 hours. Active regions NOAA 2038 (2), 2035 (1) and 2034 (2, from behind the west limb) were the sources. A CME first visible in LASCO/C2 at 15:12UT originated from a filament eruption in the northeast solar quadrant. Another CME, first visible in LASCO/C2 at 16:36UT, was related to a backside solar flare. None of these CMEs has an earth-directed component. Further C-class flaring is expected. Solar wind speed has been varying between 400 and 450km/s, with Bz between -4 and +2nT. A small equatorial coronal hole will reach the central meridian tonight. The geomagnetic field may be impacted around 27 April. Geomagnetic conditions have been quiet, and are expected to remain so.

今日估計的國際太陽黑子數（ISN）：063，基於17個觀測站。
