Bulletin

In the past 24 hours, beta region NOAA AR 2454 produced one C1.3 flare which peaked around 12:13 UT on November 23. C flares are expected within the next 24 hours, with a 10% chance for an M flare. The Earth is currently within a slow solar wind region regime. Solar wind speed varied between 290 and 350 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field ranged between 1 and 4 nT. Over the past 24 hours, geomagnetic conditions have been quiet to unsettled (K Dourbes between 0 and 3; NOAA Kp between 0 and 1). Quiet to unsettled geomagnetic conditions (K Dourbes < 4) are expected on November 24. The expected arrival of a coronal hole high speed stream may cause active (K Dourbes = 4) geomagnetic levels on November 25 and 26, with a slight chance for minor storm intervals (K Dourbes = 5).

Today's estimated international sunspot number (ISN): 061, based on 09 stations.
