In the past 24 hours, returning Active Region NOAA 2665 produced several B flares and a C1.4 flare peaking at 7:47 UT on August 1. C flares from NOAA 2665 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. Solar wind speed measured by DSCOVR jumped from about 330 to 355 km/s at 7:37 UT on August 1, just after a short peak in solar wind density. At 11:43 UT, a second jump to about 400 km/s occurred. Around 7:30 UT, the Interplanetary Magnetic Field (IMF) changed direction and started pointing towards the Sun, while its magnitude gradually rose to about 10 nT. These enhanced solar wind conditions are probably due to the arrival of the expected solar wind stream from a negative coronal hole. Bz has been mainly positive since the start of the enhanced solar wind conditions. Quiet geomagnetic conditions (K Dourbes equal to 1; NOAA Kp between 0 and 2) were registered in the past 24 hours. Active levels (K Dourbes = 4) are possible on August 1 and 2 under the influence of the aforementioned solar wind stream from a negative coronal hole, with a slight chance for minor storm conditions (K Dourbes = 5). Quiet to unsettled solar wind conditions (K Dourbes < 4) are expected on August 3.
