Bulletin
No flares in the past 24 h. No active regions visible on the solar disk. Solar activity is expected to be low.
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 420 km/s with interplanetary magnetic field magnitude of 5 nT. Geomagnetic conditions have been quiet. The solar wind emanating from a small negative polarity equatorial coronal hole may affect the Earth in 48 h (up to k = 4), quiet conditions expected until then.
