There are two active regions on the visible solar disc. There was one C-class flare in the past 24 hours, C1.2 with peak at 04:13 UT, from NOAA AR 2965. This AR has reduced its size and number of spots. For the next 24 hours, C-class flares remain possible.
No Earth directed CMEs were observed in the past 24 hours. The CME from 16 March could arrive to the Earth in the next 24 hours.
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, unless the CME from 16 March arrives to the Earth before that.
The geomagnetic conditions over the past 24 hours were quiet (K_Bel and Kp up to 2) . Similar conditions can be expected for the next 24 hours, unless the possible arrival of the CME from 16 March creates disturbed conditions (up to moderate storm levels can be expected).
Today's estimated international sunspot number (ISN): 032, based on 16 stations.
