Very low solar activity is expected for today, 20 April. The solar
wind speed is currently at background levels but is expected to become
enhanced later today in response to the arrival of effects from a
recurrent coronal hole. The geomagnetic activity is currently at quiet
levels but is expected to increase to unsettled to active conditions
later in the day. High-frequency radio communication users are advised
to use near predicted monthly frequencies.
