NOAA 2038 produced the only C flare of the period (C2 peaking at 14:59UT), just before rounding the west limb. Current imagery shows 6 sunspot groups, most having magnetically simple configurations. One region developed overnight in the northwest quadrant, while two other regions rounded the east limb. There are also a few 15-20 degrees long filaments visible near the central meridian and in the southwest quadrant. C-class flares remain possible. Solar wind speed decreased further from around 380 to 350km/s. Bz varied between -4 and +3nT, and became predominantly northward around midnight. The particle stream from a small equatorial coronal hole that passed the central meridian early on 24 April, is expected to arrive at Earth later today or tomorrow. The geomagnetic field has been quiet and is expected to remain so. Locally, a brief active interval is possible from the effect of the coronal hole.
Today's estimated international sunspot number (ISN): 057, based on 10 stations.
