Bulletin

There are four active regions on the visible solar disc. NOAA AR 2965 continues to be the most active one, although it has decreased in size in the past 24 hours. It has produced two M-class flares and two C-class flares in the last 24 hours. The strongest was a M1.5 flare, peaking at 22:46 UT, on 15 March. The other active regions have simple magnetic field configuration (alpha or beta) and have not produced any significant flares. For the next 24 hours, C-class flares are expected and M-class flares are possible.

No Earth-directed coronal mass ejections (CMEs) were observed in available coronagraph imagery in the past 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 410 km/s and an interplanetary magnetic field magnitude around 4 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 = 1-3) . Similar conditions can be expected for the next 24 hours.

Today's estimated international sunspot number (ISN): 058, based on 08 stations.
