In the past 24 hours, two low C flares were released by returning region NOAA AR 2490 behind the southeastern limb. The brightest flare was a C2.7 flare which peaked at 23:10 UT on February 19. C flares (probability 70%) are expected within the next 24 hours, with a chance for an M flare (probability 20%), especially from returning region 2490. In the past 24 hours, the solar wind speed measured by ACE gradually decreased from about 560 km/s to 490 km/s. The magnitude of the Interplanetary Magnetic Field ranged between 1 and 6 nT. Over the past 24 hours, quiet to active geomagnetic levels were registered (K Dourbes between 1 and 4; NOAA Kp between 2 and 3). Quiet to active levels (K Dourbes < 5) are expected on February 20, and quiet to unsettled levels (K Dourbes < 4) on February 21 and 22.
