Bulletin

NOAA AR 2750 (alpha magnetic field configuration) is the only active region visible on the disk. Solar activity has been very low, no flares in the past 24 h. Low solar activity 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 460 km/s with interplanetary magnetic field magnitude of 4 nT. Geomagnetic conditions have been quiet and are expected to remain so for the next 48 h. The fast solar wind emanating from a small equatorial negative polarity coronal hole might affect Earth on November 4th, but its effect will be weak (mostly unsettled conditions expected).

Today's estimated international sunspot number (ISN): 000, based on 10 stations.
