Bulletin

Solar activity was very low. No C flares were observed. Solar activity is expected to remain very low (no C flaring) for the next 24 hours. A filament eruption in the NE quadrant was observed by PROBA2/SWAP and Big Bear H alpha between about 16h and 19h UT on August 3. An associated CME was first registered by LASCO C2 at 18:12 UT. Further analysis is required to evaluate the possible geo-effects of this CME. Solar wind speed measured by DSCOVR suddenly increased from about 430 to 580 km/s between 12:00 UT and 13:50 UT on August 3, indicating the arrival of a high speed stream associated with a positive coronal hole. This implies that the earlier solar wind enhancements on August 2 and 3 were most probably due to the arrival of the CME of July 28. Meanwhile, solar wind speed has gradually increased to 620 km/s while the magnitude of the Interplanetary Magnetic Field has been around 5 nT. In the past 24 hours, quiet to minor storm geomagnetic levels were registered (K Dourbes between 2 and 5; NOAA Kp between 3 and 4). Active levels (K Dourbes = 4) are possible on August 4 and 5 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 6.
