You may also call my office at 661-395-4526 or communicate via regular postal mail at

If you need to send me a fax, fax your documents to 661-395-4328 with a prominent attention to Nick Strobel since many other people use that fax number too. After you fax your documents, send me an email alerting me to the fax.

If you find an error or something is not explained as well as you like/need, be sure to check the page on the official Astronomy Notes web site first. Many old copies of earlier versions of my astronomy material are scattered all over the web and you may be reading an old version of the page.
