Welcome to AAVSOnet!
AAVSOnet is a network of remote, robotically controlled, and automatically queued telescopes for the use of its members.
The telescopes are automatically scheduled using ACP (observation scheduling program by DC-3 Dreams) with image acquisition and telescope control by MaxIm DL. Time on the telescopes is shared between AAVSO key projects (primarily surveys and field calibrations) and AAVSO member programs. AAVSOnet telescope time is awarded on a nominally competitive basis, although the systems may be used by members for any reasonable purpose if time is available.
To request time on these telescopes, you must be a current member of the AAVSO in good standing, or have the approval of the AAVSO Time Allocation Committee. To submit a proposal to use these telescopes, please complete the AAVSOnet Proposal Form
All sky photometric survey
The AAVSO is currently performing an all sky photometric survey of stars from ~10th-17th magnitude. APASS, the AAVSO All Sky Photometric Survey has pairs of astrographs operating in Chile and New Mexico.
If you are interested in volunteering, let us know by emailing firstname.lastname@example.org.

The AAVSO sees the AAVSONet robotic telescope network as an integral part of the modern offerings of the organization. We hope you enjoy them and are able to use them effectively in your research!
We gratefully acknowledge the support of SBIG (furnishing cameras, filter wheel and spectrographs); Diffraction Limited (supplying copies of MaxIm DL); and DC3 Dreams (providing ACP and ACP Scheduler). Without this kind of vendor support, AAVSOnet would not be a reality.
And many volunteers are involved in AAVSOnet activities, including each of the site managers (John Gross, Bill Stein, Greg Bolt, Mike Linnolt, Peter Nelson and Arne Henden). Without the contributions of volunteers, their time and money, the AAVSOnet would not be possible.
