Returning Active Region NOAA 2665 produced a B9.2 flare which peaked at 9:12 UT on July 31. C flares from NOAA 2665 are possible in the next 48 hours, with a chance for M flares. 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 varied between about 320 and 380 km/s in the past 24 hours. Bz oscillated between about -5 and 4 nT. The Interplanetary Magnetic Field (IMF) was directed away from the Sun and its magnitude ranged between about 1 and 7 nT. Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 1) were registered in the past 24 hours. Active levels (K Dourbes = 4) are possible on July 31, August 1 and 2 due to the expected arrival of a high speed stream from a small negative equatorial coronal hole, with a slight chance for minor storm conditions (K Dourbes = 5).
