If you have a lot of spare time visit Australia and search this web site: http://www.ips.gov.au/index.php.
Search the site for monthly summaries like this:

This came to me from a middle school science teacher at my school. Can
anyone help with his request?


I'm looking at the EarthComm text that's published by AGI, and this
investigation that I'm talking about has to do with discovering the
correlation of sunspot activity with solar flare events. The book gives
information on yearly numbers of sunspots from 1899 to 1998, which is
okay, but I'd like to have more up to date info.

I looked and looked and looked, and finally stumbled upon this web site,
http://sidc.oma.be/sunspot-data/, where I finally found data through 2009.
I'm surprised it was so hard to track down, but anyhow I found it.

*Now I want more data on yearly solar flare events.* The text book gives
data on number of solar flare events only from 1978 to 2001.

I can't find any source on the web that gives the yearly number of solar
fare events!

Can you help me?
