This webinar will feature brief talks from three AAVSO Special Interest Groups: Eclipsing Binaries, Instrumentation & Equipment, and Short Period Pulsating Variables. The session will include a discussion of the AAVSO’s SIGs, and ways to participate. Why register? If you enjoy observing variables due to stellar alignments or pulsations, you'll be interested to hear about the ongoing studies conducted by the EB Section and SPP Objects Section. If you like learning about the hardware that we use in observing the heavens, then you’ll need to hear from the SIG dedicated to instruments and equipment.
