Bulletin

Beta region NOAA AR 2529 released one C2.9 flare in the past 24 hours, which peaked at 23:43 UT on April 13. More C flares (probability 65%) are expected in the next 24 hours, with a slight chance (probability 10%) for an M flare, especially from AR 2529. CACTUS detected a northwestward CME on LASCO C2 data starting from 17:36 UT on April 13. This CME is most probably associated with a backside filament eruption first observed in EUVI A imagery at 17:15 UT, and will not be geo-effective. In the wake of a coronal hole high speed stream, solar wind speed decreased from about 540 to 450 km/s around 6:50 UT on April 14. A weak shock in the solar wind was registered by ACE at 6:54 UT, lifting the solar wind speed to about 490 km/s. This shock probably corresponds to the expected glancing blow from the April 10 CME. The magnitude of the Interplanetary Magnetic Field decreased from 7 to 4 nT, before the shock delivered values of around 10 nT. Over the past 24 hours, geomagnetic conditions have been quiet to active (K Dourbes between 1 and 4; NOAA Kp between 2 and 4). Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on April 14, 15 and 16, with a chance for active (K Dourbes = 4) excursions on April 14.
