CHOICE in Astronomy
“You cannot teach a man anything; you can only help him discover it in himself.”
CHOICE is an education and outreach initiative of the AAVSO. It is a collection of informal, online short courses on topics chosen to help members of the AAVSO and others contribute more to science. It has two main goals towards this end. First, we hope to train participants to be better observers, analysts, researchers, writers and advocates. Second, by improving the quality of our data products and making them easier to use, it will help astronomers and researchers best utilize AAVSO data.
At a Glance
Most CHOICE courses are four weeks long. They are run via the AAVSO web site using private forums and e-mail at a self directed pace. Participants should expect to devote 8 - 20 hours per week for reading, discussions, quizzes and exams. We offer a variety of topics, from introductory to very advanced, aimed at a wide range of participants, including digital, visual and non-observers. The courses are assessed on a pass/fail basis. Those who successfully complete a course will be provided with a certficate and it will also be included on their web site's user profile page (click here for an example of a past graduate).
One of the unique aspects of this program is that courses will be peer taught. That is, graduates of one course will have the opportunity to lead the next iteration of that course. Learning occurs best when done collaboratively, and for many, the best way to learn is to teach. Those who take this opportunity will be rewarded with an extra badge on their web profile. Those who agree to lead a course will also have the registration fee waived for one subsequent CHOICE course that they elect to take. So if a member takes a course and later teaches it, they will get a certificate of completion and two badges on their user profile.
All course leaders will have access to AAVSO staff for assistance and guidance as well as access to the course syllabus, PDFs and any other materials developed for the course. In short, AAVSO staff will take care of the technical issues (registration, course materials, etc.) while the leaders are responsible for guiding the students through the course and performing any assessments.
The AAVSO has identified a number of possible course topics that fall along one of three strands: visual observing, digital observing and variable star science. Specific courses offered will be based on demand and the availability of instructors. For a complete course listing click here.
Most courses are available to AAVSO members AND the general public. The fee for AAVSO members is $30.00. Non-members pay $50.00. Registrations are available on a first-come, first-serve basis. When there are open courses registration is handled through our online store.

September 7- October 2 Registration Closed
CCD Photometry 1
Instructor- Phil Sullivan
This course will use the first half of the newly-released AAVSO Guide to CCD Photometry and will provide motivation and scientific background for doing photometry with a CCD. Topics covered include system testing and basic image calibrations from bias and dark frame subtraction to flat fielding. Students will need their own image processing software, but images will be provided for those without their own equipment.
Developing a Visual Observing Program Registration Now Open
Instructor- Mike Simonsen
This four week course is designed to help visual observers get the most enjoyment and scientific return from the observing programs they develop, based on each individuals’ equipment, observing conditions and interests.
CCD Photometry 2 Registration Now Open
Instructor- Dave Cowall
This course will use the second half of the newly-released AAVSO Guide to CCD Photometry and will cover topics including optimal image photometry settings and techniques, transformation, and basic error estimation. We'll also discuss how to plan an observing run to optimize the scientific return of your observations. Part 1 of this course is not a prerequisite, but is very strongly encouraged for new CCD photometrists. Image processing software is required, but images will be provided for those without their own equipment.
November 2- December 4 (1 week off for Thanksgiving)
This course will utilize the new DSLR photometry manual as its guide. This manual is a basic introduction and guide to using a DSLR camera to make variable star observations. The target audience is first-time beginner to intermediate level DSLR observers, although advanced observers may find the content useful as well.
About Carolyn Hurless
Carolyn J. Hurless was the most active and prolific female observer in the history of the AAVSO, with a total of 78,876 observations in the AAVSO International Database. But that only scratches the surface of this remarkable woman’s life and career as an AAVSO observer, councilor, officer, mentor and ambassador.
