Solar activity has been low and is expected to remain so for the next 24 hours. A slight chance on a C-flare is possible from AR NOAA 1806 (Catania 50). Geomagnetic activity reached minor storm levels (K=5) around 18:00 UT on August 4th due to a fast solar wind stream from a coronal hole. Geomagnetic conditions are currently quiet and are expected to remain so for the next 48 hours.
