There are no active regions or sunspot groups at the visible side of the Sun. There have also been no halo CMEs in the past few days and the solar wind is slow. As a consequence, ALL QUIET ALERT state is active since yesterday noon, meaning that in the next 48 hours we expect that the solar X-ray output remains below C-class level, the K_p index remains below 5 and the high-energy proton fluxes remains below the event threshold.
