Solar activity trends

DanSolo

Hi,

I'm looking for a general solar activity chart that covers as much history as possible (up to this month or even better today).

In a nutshell, I am looking to validate if we are in fact in a period of increasing solar activity which would apparently keep increasing until next year ?

Anyone know where I can find this ?

Thanks
DanSolo

DanSolo, Welcome to Physics Forums!

This NASA site gives observations through 30 April 2012 (yesterday) and also its predictions for the solar activity:

Hi,thanks,

I know this site but I can't find the trends per say ? The page your link leads to is for may 2009. The 2012 button leads to a news article page.

I am looking for a chart based trend (call me visual ;-))

Thanks
DanSolo

Thank you Dave. This is perfect.

Do you know if NASA has such charts ?

they probably do, I am not aware of any links
I make pretty much full time use of IPS.

I would like to create an online chart that would be generated from a real-time Sun Spot and CME data source.

Does anyone know where the official data fur such 2 events comes from and how I can get this information ?

Ideally this would be either downloadable FTP data or better, a direct database connection.

Thanks
Danny

Once again I get this data daily in emails
from both the IPS in Australia and from the Solar Terrestrial Despatch

I dont know if they offer it in a FTP data format that could be loaded directly into Excel or something

Solar activity is expected to increase though next year, and then it might peak like Solar Cycle 20 (beginning in October 1964 and ending in June 1976) in 2014.
