Bulletin

Solar activity has been low, only minor C-class flares in past 24 h. The strongest flare was a C1.1 event from NOAA AR 2288 with peak at 00:26 UT. All active regions on the solar disk have very simple magnetic configuration so the situation is not expected to change in the coming hours. The Earth is under the influence of a coronal hole related solar wind, with relatively low speeds (about 400 km/s). Conditions are unsettled and expected to remain so, with possible isolated active periods.

Today's estimated international sunspot number (ISN): 034, based on 12 stations.
