Fourteen C flares were released by NOAA AR 2497 in the past 24 hours. The brightest flare was a C4.2 flare which peaked at 17:52 UT on February 15. M flares (probability 50%) and C flares (probability 85%) are possible within the next 24 hours, especially from AR 2497. The solar wind speed measured by ACE has been gradually rising from values near 410 km/s around 4h UT on February 16, and started a sharp rise around 10h UT towards a maximum of 570 km/s around 11h UT. Current values are near 530 km/s. The magnitude of the Interplanetary Magnetic Field has been near 15 nT since about 5h UT. This may correspond to the interaction region in front of the anticipated coronal hole high speed stream. Over the past 24 hours, geomagnetic conditions have been quiet to active (K Dourbes between 1 and 4; NOAA Kp between 1 and 4). Active to minor geomagnetic storm conditions (K Dourbes = 4-5) are possible on February 16 and 17, as a result of the anticipated coronal hole high speed stream. Active geomagnetic levels are possible on February 18.
