Bulletin

NOAA AR 1904, located north of AR 1899 produced a M1.1 flare on Nov. 23, peaking at 0232 UT. There is no indication of a CME associated to that event. This region is likely to maintain a moderate level of flaring activity in the next 48 hours, essentially C flares, with a fair chance for an isolated M class event, due to its proximity with AR 1899. Active conditions are therefore foreseen for the next 48 hours. Quiet to unsettled geomagnetic conditions are currently observed at planetary and local level (Dourbes). ACE measurements show some slight excursions of the Bz component of the interplanetary magnetic field down to -10 nT. This weak disturbance is probably linked to a sector boundary crossing, that occurred late on Nov. 22. We expect mostly quiet conditions for the next 48 hours.

Today's estimated international sunspot number (ISN): 030, based on 04 stations.
