Five C-class flares occurred during the past period, with NOAA active region 2436 as the main responsible source location. The strongest event was a C6.3 flare peaking at 4:34 UT on October 21. NOAA AR 2436 has developed a delta component in its trailing part. No Earth-directed CMEs were observed. Flaring at the C-level is expected, with an increased chance for an isolated M-class flare, especially from NOAA AR 2436.

The solar wind speed was relatively stable with values below 400 km/s, until about 9 UT. Since 9 UT, the solar wind speed and temperature gradually have increased and the speed reached a maximum of 480 km/s. The magnitude of the interplanetary magnetic field (IMF) went to 13 nT with a fluctuating Bz component between -9 and 11 nT. This is indicative for the start of the expected flow from the equatorial coronal hole. Currently geomagnetic conditions are quiet (K<3) to unsettled (K=3). Up to geomagnetic active (K=4) conditions are expected in the next 24 hours.
