SIDC SOLAR BULLETIN 18 May 2012, 1237UT
SIDC FORECAST (valid from 1230UT, 18 May 2012 until 20 May 2012)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 18 May 2012  10CM FLUX: 136 / AP: 007
PREDICTIONS FOR 19 May 2012  10CM FLUX: 135 / AP: 007
PREDICTIONS FOR 20 May 2012  10CM FLUX: 134 / AP: 007
COMMENT: Solar activity has been low, only a C3.6 flare was detected
peaking at 08:23 UT from NOAA AR 1476, which is over the west limb now.
NOAA ARs 1482 and 1484 are expected to produce C-class flares and
possible small M-class flares. An eruption was seen originating in NOAA
AR 1482 around 05:00 UT, the CME is seen by COR2-A with a speed of
500km/s. It is too early to say if it will affect the Earth, but due to
the central position of this AR there is a potential danger that it
could arrive to the Earth on May 22 (no clear LASCO data yet).
Geomagnetic conditions are expected to be quiet.



TODAY'S ESTIMATED ISN  : 076, BASED ON 15 STATIONS.
