Everyone seems to have their own favourite sources of information.

I use the Space Environment Centre
http://www.sec.noaa.gov

Vast amount of resources are housed at this site.
A bit of digging in the gopher area will lead to archives of daily
measurements , alerts and forecasts.

The 3 day satellite environment plots of proton flux, electron flux, GOES
satellite Hp and the estimated Kp  is the one that I find particularly
helpful.
see last weekends chart at

gopher://solar.sec.noaa.gov/I9/plots/satenv/20000213_satenv%09%09%2B

Also 2 typical examples of forecasts
