Bülletään

Solar activity was low. There is one active region NOAA 2699 that appeared in the eastern hemisphere and produced many B-class flares and one C1.1 flare that peaked at 20:24 UT yesterday. Now, NOAA 2699 has alpha magnetic field configuration and is not expected to produce significant flares in the coming hours. Proton flux levels are at background values and are expected to remain so. No Earth-directed CMEs were observed. Solar wind speed is at 430 km/s now with interplanetary magnetic field magnitude of 5 nT. Geomagnetic conditions reached unsettled levels (K = 3) overnight due to the mild effect of the low latitude extension of the northern polar coronal hole (speeds reaching only 450 km/s and interplanetary magnetic field 9 nT). Quiet to unsettled conditions can be expected in the next 48 h.
