Bulletin

Solar activity was very low. In the past 24 hours, the Sun did not produce any C flares. C flares are possible in the next 24 hours. Solar wind speed measured by DSCOVR varied between about 580 and 735 km/s, indicative of a continued high speed stream influence. The magnitude of the Interplanetary Magnetic Field varied between about 4 and 7 nT. In the past 24 hours, quiet to unsettled geomagnetic levels were registered (K Dourbes between 2 and 3; NOAA Kp between 2 and 4). Active levels (K Dourbes = 4) are possible on August 6 under the continued influence of the coronal hole high speed stream, with a slight chance for a minor geomagnetic storm (K Dourbes = 5). Quiet to unsettled levels (K Dourbes < 4) are expected on August 7 as the high speed influence wanes, with a slight chance for active levels. Active to minor storm conditions are possible on August 8, with the expected arrival of a high speed stream from an isolated, positive equatorial coronal hole.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 037, sur la base de 21 stations.
