Very low solar flare activity is expected for today 23 April. The
Earth is currently under the influence of very high solar wind speeds
from a combined effect of the 18 April CME and high speed streams from
a recurrent,negative polarity coronal hole. As a result,the
geomagnetic conditions at earth could reach minor storm levels today
with isolated chance of major storms. Auroras may be visible tonight
(23 April) in Tasmania and possibly from the coastline of Victoria.
High-frequency radio communication users are advised to use monthly
predicted frequencies today.
