Solar activity was very low over the last 24 hours. Today's largest
flare was a C1.1 that peaked at 2009 UT. Solar activity is expected to
stay at very low levels for the next three days with the possibility
of C-class activity. Variations in the solar wind parameters during
the second half of the day seem consistent with the previously
anticipated possible glancing blow from a CME along with the arrival
of a high speed solar wind stream from a coronal hole. Geomagnetic
activity was on quiet to unsettled levels today. Solar wind stream is
likely to remain strong on 19 and 20 November, leading to rise in
geomagnetic activity levels to active to minor storm levels on 19
November and up to active levels on 20 November. This expected rise in
geomagnetic activity levels is likely to cause minor to moderate
depressions in MUFs and degradations in HF conditions on 19 and 20
