Bulletin

Solar activity was very low with at most background X-ray flux levels and no significant flaring activity observed. NOAA region 2609 (Catania group 60) has decayed while NOAA region 2610 (Catania group 58) has grown but remained inactive. X-ray flux is expected to remain below C level although the probability for C-level flaring has increased. No Earth directed CMEs have been observed in coronagraph data. Proton flux values are at background levels and expected to remain so.

Solar wind saw a stabilisation at close to nominal conditions. Solar wind was around 420 km/s. Total magnetic field was in the 3-4nT range with Bz variable and the phi angle in the negative sector. Solar wind is expected to remain nominal until later tomorrow when a moderate increase in solar wind parameters may be expected from a high speed stream associated to a positive polarity equatorial coronal hole.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 0-2, local K 0-3). Quiet geomagnetic conditions are expected with later tomorrow unsettled conditions becoming more likely and also isolated active periods possible.

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 029, na základě 12 stanic.
