Bulletin

Solar activity has been low in the past 24 hours with a few C flares observed. The strongest event was a C1.8 flare, taking place in NOAA AR 1785, on July 1st, 1516UT (peak time). We expect C flares in the 48 hours to occur essentially in AR 1785, raising the flaring forecast level to eruptive. A wide filament eruption occurred on the east limb, around 1930 UT, on July 1st. It was accompanied by a CME spotted by LASCO and COR coronagraphs, but with long data gaps. With the current available information, it is difficult to assess the true extent of the event and if it poses any risk. Based solely on its location, the risk for geomagnetic effects appears to be low. A second filament eruption took place on July 2nd, around 0000UT, near the central meridian. Due the data gap in coronagraph data, it is not known currently if a halo CME is associated with this event. We expect mostly quiet geomagnetic conditions for the next 48 hours. Current conditions in the interplanetary medium as measured by ACE are also very quiet.
