公告

Given the large number of complex, active regions on the disk, solar activity has been moderate. The strongest flare was an M1.1 flare from NOAA AR 1982, now approaching the solar West limb. For the coming days, the largest chance for major flaring comes from active region NOAA1990-Cat52 and NOAA1991-Cat59. In particular NOAA1990-Cat52 (the source of the X4.9 flare of Feb 25) is now categorised as beta-delta and is slowly increasing in size. At the time of this writing, the expected shock from the CME following the X4.9 flare has not arrived yet. ACE measurement of low energy proton fluxes are rising since Feb 26 22:00, therefore suggesting the shock is near. We expect thus active geomagnetic conditions later today. They will continue into tomorrow Feb 28 as we expect the influence of the fast solar wind stream from a (small) coronal hole.
