> SIDC SOLAR BULLETIN 05 Apr 2005, 1204UT
> SIDC FORECAST (valid from 1230UT, 05 Apr 2005 until 07 Apr 2005)
> SOLAR FLARES : Eruptive (C-class flares expected, probability >= 50%)
> GEOMAGNETISM : Active conditions expected (A>=20 or K=4)
> SOLAR PROTONS : Quiet
> PREDICTIONS FOR 05 Apr 2005 10CM FLUX: 088 / AP: 019
> PREDICTIONS FOR 06 Apr 2005 10CM FLUX: 092 / AP: 014
> PREDICTIONS FOR 07 Apr 2005 10CM FLUX: 096 / AP: 007
> COMMENT: NOAA AR 0747 seems to have the potential to produce a C-flare.
> The Earth is now inside the fast flow from the low-latitude coronal hole
> in the northern hemisphere. However, the interplanetary magnetic field
> is quite weak now (around 5 nT) and oscillates around zero. We thus
> expect the disturbed conditions to be finished soon.

>The fast flow from the low-latitude coronal hole in the northern
>hemisphere and its interaction region with the slower wind stream
>contained predominantly southward interplanetary magnetic field. It
>produced a minor geomagnetic storm - the Kp index from Dourbes reached 5
>yesterday, IZMIRAN gives the maximal value of 6 and NOAA SEC - 7 (this
>morning). We expect disturbed conditions to last for several more days,
>but at a weaker level.
