Bulletin

Solar activity was low. In the past 24 hours, new beta region NOAA AR 2571 produced several B flares and one C1.4 flare (peaking at 10:12 UT on August 5). More C flares are possible in the next 24 hours. Solar wind speed measured by DSCOVR varied between about 530 and 680 km/s, indicative of a high speed stream. The magnitude of the Interplanetary Magnetic Field varied between about 2 and 8 nT. In the past 24 hours, quiet to active geomagnetic levels were registered (K Dourbes between 1 and 4; NOAA Kp between 2 and 4). Active levels (K Dourbes = 4) are possible on August 5 and 6 under the influence of the coronal hole high speed stream, with a slight chance for a minor geomagnetic storm (K Dourbes = 5). A return to quiet to unsettled geomagnetic conditions is expected on August 7.

Today's estimated international sunspot number (ISN): 037, based on 22 stations.
