Very low levels of solar activity is expected for today, 17 December.
The solar wind is expected to increase from today as a recurrent
equatorial coronal hole reaches geoeffective location on the solar
disk. The geomagnetic conditions are expected to reach active levels
and at times may even reach minor storm levels. There is some chance
that aurora may be visible during the local night today from Tasmania
and the southern parts of Victoria, Australia. High-frequency radio
communication users are advised to use near monthly predicted
frequencies, today. An update on a CME associated with the erupting
filament that occurred around 15/1100 UT from the southeast solar
quadrant will be provided after the completion of the model runs
