We recently released a significant update to the backend systems for the AAVSO website. While most of the bugs introduced by this update have been fixed, there may still be problems we haven't fixed. If you run into a problem, please email

FYI, any one who has previously requested a sequence or recently requested a sequence, where none exists:


Please note the updated information required with any such future requests:

  • The name or designation of your variable star.
  • The coordinates of the variable star in decimal, sexagesimal or both formats (please include decimals)
  • The magnitude range of the variable, if known. (please include the Filter Letter; i.e. V, R, p, etc.....)
  • The Type of variable star (SRB, M, RCB, BLLAC, etc.....)
  • The Chart Scale you are able to work with (B, C, D, E, F, etc... or arcmin) for this request.
  • Whether you are a visual observer or a CCD (or other digital format) observer.
  • Indicate whether or not the request is “time sensitive or urgent”, as for a new or transient stellar event.

Thank you,
