:Issued: 2005 Jan 02 1422 UTC :Product: documentation at http://sidc.oma.be/products/meu #------------------------------------------------------------------------------# # DAILY BULLETIN ON SOLAR AND GEOMAGNETIC ACTIVITY from the SIDC (RWC-Belgium) # #------------------------------------------------------------------------------# SIDC URSIGRAM 50102 SIDC SOLAR BULLETIN 02 Jan 2005, 1407UT SIDC FORECAST (valid from 1230UT, 02 Jan 2005 until 04 Jan 2005) SOLAR FLARES : Active (M-class flares expected, probability >= 50%) GEOMAGNETISM : Minor geomagnetic storm expected (A>=30 or K=5) SOLAR PROTONS : Quiet PREDICTIONS FOR 02 Jan 2005 10CM FLUX: 098 / AP: 022 PREDICTIONS FOR 03 Jan 2005 10CM FLUX: 099 / AP: 028 PREDICTIONS FOR 04 Jan 2005 10CM FLUX: 100 / AP: 022 COMMENT: The CME accompanying the New Years X-flare has a speed around 1000 km/s and can arrive at earth early tomorrow, Dec 3. Active, possible minor storm conditions are expected. At the moment, the solar wind speed measured by ACE is around 800 km/s. A possible cause of this increased speed can be a coronal hole. The second part of it can influence the geomagnetic field in two or three days.
