No active regions visible on the Sun. No flares observed, nor expected.
No Earth directed CMEs in past 24 h. Solar protons have remained at background levels over the past 24 hours.
The solar wind speed is at 340 km/s with interplanetary magnetic field magnitude of 2 nT. Quiet conditions have been observed in the past 24. The solar wind from a narrow negative polarity equatorial coronal hole could arrive to the Earth today, mostly unsettled conditions can be expected then (with possible isolated active periods).
