Bulletin

Minor C-class flaring occurred from a new region (NOAA AR 2635) that emerged to the north of NOAA AR 2634. The strongest was a C1.3 flare peaking at 03:26 UT. More C-class flares can be expected.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

Geomagnetic conditions have been at k = 2-3 levels. Solar wind speed is now at 415 km/s with interplanetary magnetic fields of 5 nT. The expected high speed stream (HSS) from the equatorial coronal hole has missed the Earth. Quiet geomagnetic conditions expected.

Today's estimated international sunspot number (ISN): 017, based on 01 stations.
