Bulletin

The strongest flare reported in the last 24 hours was the B3.4 flare (peaked at 17:57 UT on March 1), which originated from the Catania sunspot group 27 (NOAA 2506). Although the probability for the C-class flares is low (about 20%) they are still possible, in particular from the unnamed active region which just rotated from the behind of the East solar limb. The prominence eruption was observed at about 08:00 UT on March 1, with the source region close to the East solar limb. The prominence eruption was associated with rather slow CME (speed reported by the CACTUS software is about 500 km/s) with angular width of about 115 degrees. No Earth directed CMEs were observed in the last 24 hours. The solar wind speed has increased and its current value is about 450 km/s, the interplanetary magnetic field magnitude is about 10 nT. The small equatorial corona hole has reached the central meridian this morning. The associated fast solar wind can be expected on Marc 5. The geomagnetic conditions are quiet to unsettled. Currently the Bz component of the interplanetary magnetic field is positive however if the Bz component turns negative we can expect unsettled to active conditions in the coming hours.

Today's estimated international sunspot number (ISN): 069, based on 18 stations.
