Solar activity has been low in the past 24 hours, with only C class flares. One noticeable event, a C3.3 flare, took place in NOAA AR 2066 on May 17, 0229 UT (peak time). There is no clear signature of a CME associated with that event. Two wide CMEs were observed in the past 24 hours. The first one, on May 16, 1424 UT is associated with a backside flare. The second one, on May 17, 0125 UT, is associated with a filament eruption, also on the backside. We expect eruptive conditions in the next 48 hours, with risks of C flares from NOAA ARs 2063 and 2066. Geomagnetic activity has been very low in the past 24 hours. We expect quiet conditions to prevail for the next 48 hours.
