SIDC SOLAR BULLETIN 19 Mar 2012, 1238UT
SIDC FORECAST (valid from 1230UT, 19 Mar 2012 until 21 Mar 2012)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 19 Mar 2012  10CM FLUX: 098 / AP: 006
PREDICTIONS FOR 20 Mar 2012  10CM FLUX: 095 / AP: 003
PREDICTIONS FOR 21 Mar 2012  10CM FLUX: 093 / AP: 009
COMMENT: Solar activity was very low and is expected to remain so, with
only an occasional C flare and a slight possibility of an M flare from
active region Catania 66 (NOAA 11435). Mostt active regions on the solar
disk are small or decaying. A weak disturbance reached the Earth late on
March 18, causing temporary unsettled to active geomagnetic conditions.
It is now decaying with a solar wind speed around 500 km/s. We thus
expect a return to quiet geomagnetic conditions for the next two days.
Late on day 3 of the forecast, conditions may become unsettled under the
influence of a small coronal hole now passing the solar central meridian.

TODAY'S ESTIMATED ISN  : 048, BASED ON 19 STATIONS.
