Bulletin

Solar activity was moderate in the past 24 hours, with NOAA AR 1904 producing a M1.0 flare on Nov. 23, 1257 UT peak time, and numerous C flares. This region should keep during the next 48 hours the same level of activity consisting on C flares and a chance for an isolated M class event. In the meanwhile, NOAA AR 1905, close to the East limb is likely to produce C class flares during the same period. Active conditions are therefore expected. Quiet geomagnetic conditions are expected for the next 48 hours. A slight increase to unsettled conditions with an isolated period of active conditions is possible by the end of Nov. 26 as a small coronal hole in the northern hemisphere becomes geoeffective.

Today's estimated international sunspot number (ISN): 051, based on 09 stations.
