A little off topic, but things are slow on the reflector today. %^)

Does anyone know where a ham like me [or you] could find real time critical 
F2 frequency data?  You know, the critical frequency below which the F2 layer 
reflects radio waves?  My usual source 
<http://www.ips.gov.au/asfc/data/ion/usa/rusmap.gif> has been bungled since 
the 6th of April 2100 UTC.

Ten Tec Tie In:  I'll be using my Corsair I during the QRP contest this 
weekend, and want to know when to kick in the NVIS aerial, and when I should 
move onto other modes of RF radiation.

Thanks and 73,
