Bulletin

Beta region NOAA 2670 (= returning NOAA 2665) produced a few low B flares and a B9.4 flare peaking at 23:59 UT on August 2. C flares from NOAA 2670 are possible in the next 48 hours, with a chance for an M flare. No earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels. In the past 24 hours, solar wind speed registered by DSCOVR gradually decreased from about 425 to 360 km/s. The Interplanetary Magnetic Field (IMF) was mainly oriented towards the Sun, and its magnitude varied between about 1 and 7 nT. Bz varied between about -4 and 6 nT and was only briefly below -5 nT between 12h and 13h on August 2. Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to unsettled solar wind conditions (K Dourbes < 4) are expected on August 3. Active to minor storm conditions (K Dourbes = 4 to 5) are possible on August 4 and 5, with the expected arrival of a high speed stream from a large positive coronal hole extending from the north pole to the equatorial region.
