公告

Solar activity was relatively quiet, with only NOAA Active Region (AR) 2373 producing two C class flares in the last 24 hours, A C2.3 flare peaking at 14:55 UT and a C2.4 flare peaking at 18:07 UT. Other recurrent active regions are rotating into view now and may increase solar activity in the coming days. Proton levels are still declining and are now below 1 pfu. The solar wind speed has remained roughly constant over the past 24 hours, and has varied between 360 km/s to 440 km/s. The total magnetic field has been slowly decreasing from 6 nT to 3 nT, and the Bz component has fluctuated from positive to negative between +6 and -5 nT, but remained around 0 nT for the past several hours. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 1-3 over the past 24 hours. There were no significant CMEs over the past 24 hours. A small CME emerged from the East solar limb, possibly from AR 2375. The CME had a recorded velocity of 625 km/s but is not expected to be geoeffective.
