Bulletin

Solar activity once more was very low. No active regions are visible. No flares or CMEs were observed. The solar activity is expected to remain low for the next 48 hours.

Solar wind observations indicate the presence of a co-rotating interaction region (CIR) preceding a coronal hole high speed stream. The magnitude of the interplanetary magnetic field abruptly increased around 6h30 UT to a maximum of 16 nT, with a varying Bz. The solar wind speed (currently 430 km/s) and temperature are also increasing. Geomagnetic conditions were mainly quiet, but indicate the starting influence of the solar wind disturbance (local K at Dourbes and NOAA estimated Kp currently are at K=4). Geomagnetic conditions up to minor storm levels (K=5) can occur within the next 24 to 48 hours.

Today's estimated international sunspot number (ISN): 000, based on 27 stations.
