Bulletin

There is only one active region observed on the visible side of the solar disc, NOAA AR 2597. Solar activity is low with one C-class flare reported during last 24 hours. The C 1.3 flare which peaked at 19:14 on September 25 originated form NOAA AR 2597. We can expect isolated C-class flares in the coming hours. No Earth directed CMEs were observed in the last 24 hours. The solar wind speed is presently about 410 km/s. The interplanetary magnetic field magnitude is about 10 nT, and the Bz component of the interplanetary magnetic field is about -6 nT. Due to longer interval of the negative value of the Bz component, disturbed geomagnetic conditions were reported in the evening and around midnight of September 26 (local station at Dourbes reported interval with K=5 and NOAA reported interval of Kp=5). The fast flow associated with the large, low latitude extension of the northern polar coronal hole which crossed central meridian on mid-day of September 25 is expected to arrive at the Earth in the late evening of September 27 or early morning of September 28. We expect that arrival of fast solar wind will induce disturbed geomagnetic conditions (up to Kp=6). The geomagnetic conditions are presently unsettled to active, and we expect them to stay so in the coming hours.
