SIDC SOLAR BULLETIN 31 Dec 2005, 1253UT
SIDC FORECAST (valid from 1230UT, 31 Dec 2005 until 02 Jan 2006)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 31 Dec 2005  10CM FLUX: 090 / AP: 010
PREDICTIONS FOR 01 Jan 2006  10CM FLUX: 090 / AP: 007
PREDICTIONS FOR 02 Jan 2006  10CM FLUX: 090 / AP: 017
COMMENT: The solar activity remains very low, and the small sunspot
groups currently present on the solar disc can only produce occasional C
flares.
The solar wind speed has decayed furher down to 500km/s and the
geomagnetic activity is expected to settled down to quiet levels over at
least the next 2 days. Given its slow speed, the CME of Dec.29 could at
most induce temporary active conditions on day 3 (Jan.2).

TODAY'S ESTIMATED ISN  : 038, BASED ON 01 STATION.
