AAVSO Webinar - Introductory Spectroscopy (9 Mar)

The AAVSO is conducting a series of How-To Webinars with the topic for the next one on 9 Mar being "Introductory Spectroscopy", conducted by Bob Buchheim and myself.  See the announcement on the AAVSO home page for more information and registration.

Also, the following Wed 13 Mar is the monthly meeting of the Spectroscopy Section - the topic of discussion being slitless spectroscopy.  If you're planning on attending and currently doing or contemplating doing spectroscopy sans slit, then please support the discussion with your experiences, ideas, methods, questions, observing projects, and anything else you want to discuss about this topic.
