Hello stanford4,

I'm assuming that you are working on the project described at this url:

The bibliography has a reference for an online catalog of sunspot data (Van der Linden). I think that the sunspot data that you want are within that site at this link:

I hope this helps and good luck with your project. Please post again if you have more questions.
