Bülletään

Solar activity was very low, featuring only 2 C-class flares (C1.0 and C1.4), with a source region near NOAA AR 1830. All active regions were quite stable. Solar activity is expected to be low, with a slight chance for C-class flares. No Earth directed CMEs were observed. ACE observed a small shock in the solar wind data at 00h00 UT this night, indicating the arrival of a CME, possibly that of 20 or 21 August. Solar wind speed currently is around 500 km/s. The magnitude of the interplanetary magnetic field had a maximum of 9 nT, with a Bz component fluctuating between +5 and -5 nT. Current geomagnetic conditions are unsettled. We expect unsettled to minor storm levels for the next 48 hours, related to the CME arrival, possibly combined with some minor influence of a coronal hole fast speed stream.
