We zij dus nog hoopvol. CME wordt verwacht in de late avond of vroege nacht.
PRESTO FROM SIDC - RWC BELGIUM Thu Nov 11 2004, 1322 UT
The magnetic storm is now declining and active or minor storm conditions are now observed. The solar wind speed has now decreased to 600km/s and Bz remains near 0. For a few hours, we thus expect unsettled to active geomagnetic conditions. However, the halo CME associated with the Nov. 10 X2.5 flare is expected to hit the magnetosphere late today Nov. 11 or early on Nov. 12. and to induce a major or severe magnetic storm. The magnetosphere should become quiet again on Nov. 13. The source region, #61 (NOAA686), has been steadily declining over the last 3 days, and no significant flare occured after the Nov. 10 X flare. However, it keeps a beta-gamma-delta magnetic configuration and can still produce M flares and an isolated X flare before desappearing at the West limb tomorrow, Nov. 12.
