The solar disk remains covered with a large number of sunspot groups, many of them undergoing magnetic reconfigurations and producing non-stop C-class flares. The most noteworthy regions are AR1987-Cat49 (beta-gamma), AR1990-Cat52 (beta-delta), AR1991-Cat59 (Feb 28 M1.1 flare), AR1982-Cat 46 (beta-gamma). As a consequence we expect M-class flaring activity but an isolated X-class flare also remains possible. AR1982-Cat 46 will rotate behind the solar West limb in the coming 48 hours, a sharp drop in the F10.7 radio flux can thus be expected. We expect continued episodes of K=4 activity during the next 24 hours as a consequence of a fast solar wind stream from a recurrent coronal hole. ACE low energy proton fluxes also suggest that a new shock might arrive in the coming 12 hours.
