Very low solar activity is expected for today, 13 Jan. The solar wind
speed is currently light but may become enhanced during the day due to
the expected arrival of a high speed stream from a recurrent coronal
hole. The geomagnetic activity is expected to start the day at quiet
levels then increase to active levels once the high speed winds
arrive. High-frequency radio communication users are advised to use
slightly lower than the monthly predicted frequencies.
