Bulletin

Flaring activity during the last 24 hours was limited to four C-class flares. The strongest flare was a C4.1 flare peaking at 22:05 UT on March 30 originating from the NOAA active region (AR) 2303, located right behind the west limb. We expect flaring activity at the low C-level in the next 48 hours, potentially from NOAA ARs 2315 and 2316. No Earth-directed CMEs were observed. The Earth is still inside a slow solar wind flow. A shock-like signature was observed in the solar wind data observed by ACE and SOHO/CELIAS. Solar wind speed (to about 400 km/s), density and the magnitude of the interplanetary magnetic field (IMF) jumped at around 7:40 UT on March 31. The z-component of the IMF is varying between -13 and +11 nT. The solar source of this disturbance in the solar wind is unclear at this moment. A CME from March 27 (first measurement in LASCO-C2 at 13:36 UT) and a CME of March 28 (fist detected in LASCO-C2 around 10:37 UT) are two potentially associated events. No geomagnetic disturbances are noted yet. Geomagnetic activity up to the minor storm level is expected, due to the combined influence of the arrived shock-like structure and the fast flow from a low-latitude extension of the southern polar coronal hole, which is expected to arrive in the course of today.

Today's estimated international sunspot number (ISN): 031, based on 15 stations.
