The Sun produced 3 C flares in the past 24 hours. The brightest flare was a C4.6 flare released by NOAA AR 2469 which peaked at 05:09 UT on December 18. C flares are possible within the next 24 hours, with a chance for an M flare. During the past 24 hours, the solar wind speed gradually decreased from about 470 to 400 km/s with intermittent peaks up to 550 km/s. The magnitude of the Interplanetary Magnetic Field varied between 1 and 8 nT. During the past 24 hours, quiet to unsettled geomagnetic levels were registered (K Dourbes between 1 and 3, NOAA Kp between 1 and 4). Quiet to unsettled geomagnetic conditions (K Dourbes < 4) are expected on December 18. Due to the expected arrival of the December 16 CMEs, active to minor storm conditions (K Dourbes = 4-5) are expected on December 19, with a chance for moderate to major storm conditions (K Dourbes = 6-7). Quiet to unsettled geomagnetic levels are expected on December 20, with a chance for active (K Dourbes = 4) excursions.
Today's estimated international sunspot number (ISN): 047, based on 07 stations.
