Bulletin

NOAA AR 1893 produced an X1.0 flare on Nov. 19, peaking at 1026 UT. It was accompanied by a metric type II burst, and an EUV coronal wave. A CME was associated with this event, as observed by COR2 A, but only one image is available and its speed is currently unknown. A preliminary analysis, which will be updated as new information comes in, makes this event unlikely to be geoeffective. Currently there is no consequence on the proton flux, but a rise in coming hours is not impossible. We foresee active conditions to prevail for the next 48 hours, with risk of M flares from NOAA ARs 1893 and 1897. NOAA AR 1893 developed a delta configuration (which probably explains the X flare of this morning), and an isolated X class flare is not excluded. Until further analysis is performed on the CME linked to the X class flare of this morning, we expect quiet geomagnetic conditions to prevail for the next 48 hours. A CME spotted on the South-East limb on Nov. 19, around 0430 UT (LASCO C2) appears to be backsided. Current interplanetary conditions as measured by the ACE spacecraft are very quiet.
