This webinar will feature introductions to three AAVSO Special Interest Groups: Exoplanets, Young Stellar Objects, and Solar Observing, and will include a discussion of how to participate in the groups -- and how to contribute to scientific knowledge! Why register? If you enjoy observing exoplanets or probing protostars, you'll be very interested to hear about the ongoing studies conducted by the Exoplanet Section and Young Stellar Objects Section. If you’re curious about sunspots, flares and other features of our nearest star, then you’ll need to hear from the SIG dedicated to Sol.
