Our quarterly magazine, the REFLECTOR, is published in March, June, September and December. If you belong to an astronomical society that belongs to the Astronomical League, your membership in that society includes a subscription to the the Reflector. If your society does not belong to the League, you can join us by having one of your officers contact us for further information on membership.
You can also join the Astronomical League as a Member-at-Large. If all you want is to subscribe to the Reflector, then there is a subscription form here.
