Bülletään

In the last 24 hours two M flares were detected by the GOES satellite: a moderate M1.3 flare, in NOAA AR 1731, at 1655 UT (peak time), and a M5.7 flare in NOAA AR 1739, at 1732 UT (peak time). This region should be monitored for further M class flares in the coming days, as it begins its transit on the disk. AR 1731 is still complex enough to produce an isolated (but likely moderate) M flare as well, and we foresee active conditions for the next 48 hours. AR 1734 is likely to produce C flares with a slight chance of an M class event. The M5.7 flare was associated with a wide CME spotted on the East limb (at 1800 UT on LASCO C2), with an estimated speed of at least 600 km/s (CACTUS detection). Another CME took off to the south of AR 1739 at 2200UT. We do not expect these events to be geoeffective. A filament eruption took place near the central meridian (about 15 degree North), on May 4th around 0245 UT but no CME can be linked to this event. We expect geomagnetic activity to reach active conditions by the end of May 4 beginning of May 5 due to a coronal hole and its associated high speed solar wind stream. Active conditions might continue on May 6 due to the arrival of the CME of May 2nd.
