Skrót wiadomości

Solar activity was at very low levels. The 3 visible sunspot groups were quiet. The greater than 10 MeV proton flux was at nominal levels. Quiet flaring conditions are expected, with a small chance on a C-class flare.

Some coronal dimming was observed at S10W50 on 01 October between 14 and 17UT, followed by post-eruption coronal loops over and to the northwest of NOAA 2682. The x-ray flux seems to have been mildly enhanced in response to this eruptive event. Some coronal mass ejections (CMEs) were observed by SOHO/LASCO starting late on 01 October, but they were relatively slow (CACTus) and directed to the west (no obvious earth-directed component).

Solar wind speed varied between 430 and 500 km/s (DSCOVR), ending the period near 440 km/s. Bz varied between -5 and +2 nT (DSCOVR). The interplanetary magnetic field was mostly directed away from the Sun. A small negative equatorial coronal hole (CH) started transiting the central meridian on 01 October.

The geomagnetic field was at quiet to unsettled levels, with Kp featuring a single active episode during the 03-06UT interval. Quiet to unsettled geomagnetic conditions are expected, with an active episode still possible. The arrival of the particle stream associated with the aforementioned CH is expected for 04 or 05 October, with increasing chances on active geomagnetic conditions.
