公告

The strongest flare over the last 24 hours was a C2.7 peaking on 2 August at 13:28UT and produced by NOAA 2132. Together with NOAA 2121 and 2134, it produced only low-level C-class flares. The two 25-degrees long filaments in the NE and SW quadrant remained stable. No Earth-directed CMEs were observed. C-class flaring is expected, with a small chance on an M-class flare from NOAA 2130, 2132 and 2134. Solar wind speed decreased from an initial value near 450 km/s to about 390 km/s. Bz started out mostly negative near -8 nT, after which positive values dominated up to a maximum of 5 nT. There was no obvious signature in the solar wind parameters of a passing-by of the 30 July CME. Geomagnetic conditions were initially unsettled in Dourbes, with Kp even briefly reaching 4. Afterwards, quiet to unsettled conditions prevailed. Geomagnetic conditions are expected to be quiet, with some unsettled conditions possible later today and tomorrow under the influence of a coronal hole stream and the possible glancing blow from a CME related to the M-flares on 1 August. Locally, a brief active episode is not excluded.
