SIDC SOLAR BULLETIN 26 Nov 2004, 1204UT
SIDC FORECAST (valid from 1230UT, 26 Nov 2004 until 28 Nov 2004)
SOLAR FLARES : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 26 Nov 2004 10CM FLUX: 113 / AP: 012
PREDICTIONS FOR 27 Nov 2004 10CM FLUX: 115 / AP: 012
PREDICTIONS FOR 28 Nov 2004 10CM FLUX: 116 / AP: 012
COMMENT: We are leaving the influence zone from the small coronal hole. The
solar wind speed is at present 450 km/s. The last C2.6 flare recorded by GOES
yesterday (25/11) at 10:58 UT did not originate from sunspot group catania 78
(NOAA 0706), but from returning region Catania 61 (NOAA 0696), which has
produced several X-flares and halo-CMEs during the previous rotation. Hence we
expect eruptive to active solar conditions for the next days.
