The solar activity remains low, as it was during the whole week, with mostly low C-class flares reported. The strongest flare reported in last 24 hours was C2.2 flare which peaked at 05:26 UT this morning. The flare originated from the Catania sunspot group 13 (NOAA AR 2305) which has slightly increased in the size and the sunspot number but has retained the beta-gamma configuration of its photospheric magnetic field. We expect C-class flares and possibly, but not probably also an isolated M-class flare. No Earth directed CMEs were observed during last 24 hours. The Earth is inside a slow solar wind with the speed of about 420 km/s. The interplanetary magnetic field has increased this morning and reached value of about 11 nT, this increase is probably due to the passage of the transient structure in the slow solar wind. At the same time the Bz component of the interplanetary magnetic field had 2 hours long interval of its negative value, amounting about -8 nT. The fast flow associated with the extend of the southern polar coronal hole might be expected in the afternoon of March 30. The geomagnetic conditions are quiet and expected to remain so in the coming hours.
