公告

Solar activity remains low with only low C-class flares reported. The strongest flare in last 24 hours was a long duration C3.8 flare (peak time at 06:54 UT) observed this morning. The flare originated from the Catania sunspot group 43 (NOAA AR 2056) currently situated at the west solar limb. From the currently available data it seems that the flare was associated with a rather narrow CME. We expect flaring activity on the C-level. The Earth is still inside a slow solar wind flow with the speed of about 350 km/s. The interplanetary magnetic field magnitude is 4 nT. The geomagnetic conditions are at the moment quiet and expected to remain so in the following 48 hours.

今日估計的國際太陽黑子數（ISN）：098，基於21個觀測站。
