There are four active regions on the visible solar disc. NOAA AR 2965 has decayed into a beta magnetic field configuration, it has decreased in size and produced the only C-class flare of the past 24 hours (C1.0 with peak at 19:18 UT on 17 March). The other regions are small and have simple magnetic field configurations. For the next 24 hours, C-class flares can still be expected.
No Earth directed CMEs were observed in the past 24 hours. The CME from 16 March may arrive to to the Earth on 20 March.
The greater than 10 MeV proton flux was at nominal levels and is expected to remain so in the next 24 hours. The greater than 2MeV electron flux was under the 1000 pfu threshold and is expected to remain so for the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so in next 24 hours.
The Earth is inside a slow solar wind flow, with solar wind speeds close to 300 km/s and an interplanetary magnetic field magnitude around 5 nT. Similar conditions are expected for the next 24 hours.
The geomagnetic conditions over the past 24 hours were mostly quiet (K_Bel = 1-3 and Kp = 2) . Similar conditions can be expected for the next 24 hours.
Today's estimated international sunspot number (ISN): 033, based on 17 stations.
