Recurring Donations - Just $10 a month can make a tremendous difference!

Become a monthly donor! A recurring donation to our giving circle of friends is the easiest and most efficient way to support the Astronomical Society of the Pacific’s creation of materials, resources, and programs to promote public science interest, engagement, and literacy through the awe and wonder of astronomy and related fields.

You can easily start, change or stop your gift at any time online or by phone.

Our special Thank-you gifts change every calendar year. Recurring donors will receive a gift when they reach the giving goals of $100, $500, and $1000 and above.

Please contact Membership at or 415-715-1400 if you wish to donate your goal gift, or do not wish to receive these special gifts.
