Bulletin
A single minor B1.1 flare occurred from a new bipolar sunspot group emerging from around midnight near N05E10. Chances for C-class flaring remain very low.
No Earth directed CMEs have been observed in coronagraph images.
Proton flux levels were at background values and are expected to remain so.
A small negative polarity equatorial coronal hole crossed central meridian overnight.
Solar wind was nominal with solar wind speed in the 320-370 km/s range and total magnetic field below 5nT. The magnetic field phi angle is in the negative sector. Nominal conditions are expected over the next days with from November 26 minor enhancements possible due to the relatively small equatorial coronal hole.
Geomagnetic conditions were quiet (local K Dourbes and NOAA Kp 0-1) and are expected to remain so, with from November 26 unsettled conditions possible.
Today's estimated international sunspot number (ISN): 007, based on 03 stations.Solar indices for 23 Nov 2018
