Bulletin

Solar activity was very low, with no x-ray flaring observed. The sole sunspot region that is currently visible, NOAA 2603, is small and decaying. No earth-directed coronal mass ejections (CMEs) were observed.

Solar flare activity is expected to remain below the C-class level.

Solar wind speed decreased from about 440 km/s to its current values near 380 km/s. Bz fluctuated between -8 nT and +6 nT, and was mostly negative. Quiet to unsettled geomagnetic conditions were observed, with an isolated active episode near midnight. The interplanetary magnetic field was mostly directed away from the Sun (positive). A huge, positive, recurrent coronal home (CH) is transiting the central meridian.

Mostly quiet to unsettled geomagnetic conditions are expected until the arrival of the co-rotating interaction region (CIR) preceding the high speed stream (HSS) from the aforementioned CH. This arrival is currently foreseen for 25 October, with minor geomagnetic storming possible from then onwards. There's a good chance on an isolated moderate storm interval (K-index = 6).

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 015, na základě 04 stanic.
