Bulletin
Solar activity has been very low, no C-class flares in past 24 h. All the active regions on the visible solar disk have simple configuration, only C-class flares can be expected. Geomagnetic conditions are quiet and expected to remain so until the arrival of the fast speed stream from a small equatorial coronal hole within 48 h. The solar wind speed is currently at 350 km/s with interplanetary magnetic field intensity of 5 nT.
