About the Club

The Pajarito Astronomers is a club consisting of approximately 30 professional and amateur astronomers from throughout northern New Mexico. For annual dues of $10, club members are provided the Abrams Planetarium monthly astronomical events calendars and monthly newsletters that include both astronomical and club information. Members may check out books from the club's reference library. Members can also receive discounts on selected astronomy-related items. Membership form.

From late-spring to early-autumn, the Pajarito Astronomers Club holds County-Sponsored "Dark Night" observing sessions at Overlook Park in White Rock, New Mexico. These sessions are open to the public and occur once a month (on a Saturday evening near a new moon) when Los Alamos County turns off all the athletic field lights at the park. A typical session will have 50-100 people looking through 5-10 telescopes, viewing galaxies, planets, star clusters, the moon, and much more. Weather permitting, observing sessions start at sunset and end before 1 AM.

As a community service, the Pajarito Astronomers sponsors public talks in Los Alamos. Invited speakers cover a wide variety of topics in space science, astronomy, and astrophysics.

The club also provides awards at the Los Alamos science fair for space science and astronomy projects. Several times a year, upon request, club members provide constellation tours of the night sky, telescope tours of the night sky, or astronomy lectures to organizations or school classes. And occasionally throughout the year, club members provide planetarium shows at schools or fairs. The planetarium is typically provided by the group requesting a show, or provided through Los Alamos National Laboratory's educational outreach office.

Club events are announced in the Los Alamos Monitor (, the Los Alamos Daily Post ( and KRSN-1490. For more information about the Pajarito Astronomers, contact Steve Becker (667-8964), Dave Hollowell (662-4272) or Don Casperson (667-1475).

Staying on Rt. 4 for 4 miles, enter White Rock and turn left at the first street, Rover Blvd. Go one block and turn left onto Meadow Lane. Follow Meadow Ln. 3/4 of a mile and turn left into Overlook Park. Spirio Soccer Field is the first large field on your right, just before the concession stand building. When you enter the parking lot, please dim your car lights so that you do not interfere with the observations.
