Here's a few I use:

http://www.swpc.noaa.gov/Aurora/globeSE.html
http://www.ips.gov.au/Space_Weather
http://www.swpc.noaa.gov/pmap/
http://www.swpc.noaa.gov/pmap/pmapS.html
http://www.ips.gov.au/Geophysical/4/1
http://www.spaceweather.com/

Some of them you need to use in combination, but I lately I like the 2nd last one.
