Bülletään

The Sun produced two low C flares during the past 24 hours. NOAA AR 2388 released a C1.8 flare peaking around 14:42 UT on July 18, which was accompanied by a Type II radio burst and a CME first observed in LASCO C2 at 15:12 UT. This CME is not expected to be geoeffective. A large filament eruption took place between about 10W 25N and 60W 10S, starting around 1h UT on July 19. This eruption seems to have triggered a smaller filament eruption between about 55W 30S and 85W 20S around 8h UT, as well as the C2.0 flare released by AR 2384, which peaked around 10:43 UT. Two faint CMEs detected in LASCO C2 images, starting at 3:48 UT and 5:24 UT respectively, may be related to the first filament eruption, but none of these CMEs is expected to be geoeffective. More C flaring is possible, with a slight chance for an M flare. 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 geomagnetic conditions (K Dourbes < 3) are expected on July 19. Quiet to unsettled levels with active (K Dourbes = 4) excursions are possible on July 20 due to the expected arrival of a coronal hole high speed stream. Quiet to unsettled conditions are likely on July 21.
