Support the Astronomy Notes Site!

This site does not have any advertising except for this annoying message and a notice about purchasing the hardcopy Astronomy Notes book. This site is provided out of the generosity of its author, Nick Strobel. However, providing this service can be expensive for a family living on one teacher's salary.

Therefore, here is my request: If you have found this site useful, would you send me a contribution (in US $, please)?

You select the amount, but please note that PayPal takes $3.20 as a transaction fee---the remainder of your donation goes to helping me keep this site up and running. Note: You do NOT need a PayPal account to make an electronic donation---any credit card will do. If you feel better about sending a check, then send a check payable to "Nick Strobel" to
