Bulletin

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 550 km/s with interplanetary magnetic field magnitude of 4 nT. The Earth is inside the high speed stream from a negative polarity coronal hole. The solar wind speed peaked yesterday at 584 km/s, with interplanetary magnetic fields up to 10 nT. Active geomagnetic conditions were observed locally (K Dourbes = 4) and unsettled at planetary levels (Kp = 3). Mostly unsettled conditions are expected in the next 48 h (active periods remain possible).

Today's estimated international sunspot number (ISN): 000, based on 23 stations.
