Solar activity has been eruptive during the past 24 hours, featuring three C flares, from NOAA AR 11777 and 11778. The brightest flare was a C7.3 flare released by NOAA AR 11778 with peak time at 03:37 UT on June 28. More C flares are possible within the next 48 hours, with a chance for an M flare. NOAA AR 11777 released two CMEs (observed by LASCO C2 at 20:37 on June 27 and 02:00 on June 28). The first CME is not expected to be geo- effective, while there is a slight chance for a glancing blow from the second CME on July 1st. ACE detected a shock in the solar wind at 13:53 UT on June 27, probably due to some unidentified CME. The solar wind speed jumped from about 380 km/s to around 460 km/s, and has currently decreased again to 365 km/s. The IMF jumped from 3 to 8 nT, has subsequently further risen to 12 nT near 2h UT on June 28, and has since been gradually decreasing, with current values around 9 nT. Geomagnetic activity was at quiet to active levels (K Dourbes between 1 and 4) during the past 24 hours. Quiet to active conditions (K Dourbes < 4) are expected for June 28, with a chance for a minor geomagnetic storm (K Dourbes = 5). On June 29, quiet to active levels (K Dourbes = 4) with minor storm periods are possible as a consequence of the expected arrival at Earth of a new coronal hole high speed stream. Quiet geomagnetic levels (K Dourbes < 4) are likely on June 30.
