公告

Six sunspot groups are reported by Catania today. The main source of the solar flaring activity is the Catania sunspot group 88 (NOAA AR 2192) that is growing in size and complexity. Now it has beta-gamma-delta configuration of its photospheric magnetic field. After yesterday's X1.1 flare, the strongest flare was the M3.9 flare peaking at 09:11 UT today. This flare was not accompanied by a CME. We expect more flaring activity up to X-level from this sunspot group. The Earth is currently inside a solar wind flow with intermediate speeds (around 500-550 km/s). This flow might be associated with a narrow low-latitude coronal hole that passed the solar central meridian on October 17-18. The interplanetary magnetic field (IMF) magnitude was elevated (up to 9 nT), and the IMF was directed predominantly southward during the last several hours. Intervals of active geomagnetic conditions (K = 4) were reported by Dourbes and NOAA. We expect quiet to active geomagnetic conditions in the coming hours.
