Bulletin

Solar activity was very low. No C flares or halo CMEs were observed. Solar activity is expected to remain very low (no C flaring) for the next 24 hours. Solar wind speed measured by DSCOVR suddenly increased from about 355 to 385 km/s around 12h UT on August 2, and gradually further to a maximum of about 460 km/s, after the solar wind density and the magnitude of the Interplanetary Magnetic Field had been rising since about 4h UT to a maximum of about 40 particles per cc and 25 nT, respectively. These phenomena are most probably due to the arrival of a predicted high speed stream associated with a positive coronal hole. In combination with Bz values of down to -20 nT, this resulted in active periods for K Dourbes and even minor geomagnetic storm periods for NOAA Kp between 21h UT on August 2 and 9h UT on August 3. Further active to minor geomagnetic storm periods (K Dourbes = 4-5) are possible on August 3. Active conditions are possible on August 4, and a return to quiet to unsettled geomagnetic conditions is expected on August 5.
