Bulletin

The only C-class event of the period was a C1 flare peaking at 09:54UT and produced by NOAA 2178. The 7 groups currently visible on the solar disk have a relatively simple magnetic configuration and have been quiet. Numerous filaments are present on the solar disk, but they are mostly small and quiet. There remains a chance on an C-class flare. No obvious CMEs were observed during the period. A corotating interaction region has influenced the solar wind since late on 3 October. Around 17:00UT on 4 October, the direction of the IMF turned towards the Sun, and solar wind speed peaked near values of 480 km/s early on 5 October. Bz was mostly positive, fluctuating between -5 and +10 nT during the latter half of the observation period. Geomagnetic conditions were quiet to unsettled and are expected to remain so.

Today's estimated international sunspot number (ISN): 068, based on 11 stations.
