The Sun did not produce any C flares in the past 24 hours. Quiet conditions (no C flares) are expected within the next 24 hours. The magnitude of the Interplanetary Magnetic Field gradually rose from 4 to 9 nT. Around 4h UT on November 27, the speed of the solar wind increased rapidly from 260 to 330 km/s. This increase was accompanied by a sector boundary crossing (first away from the Sun, after 4h UT towards the Sun). Over the past 24 hours, geomagnetic conditions have been quiet to unsettled (K Dourbes between 0 and 3; NOAA Kp between 0 and 3). Quiet to unsettled (K Dourbes < 4) conditions are expected on 27, 28 and 29.
Today's estimated international sunspot number (ISN): 057, based on 13 stations.
