Bulletin
Magnetograms show emerging magnetic flux next to NOAA AR 1644. The overall X-ray radiation is however low. A small equatorial coronal hole is now located near the central meridian. Last rotation, it did not cause any geomagnetic disturbance. An all-quiet alert is issued.
Today's estimated international sunspot number (ISN): 036, based on 11 stations.
