SID Software

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

Two software packages are typically used by SID observers. One is the data taking or logging software, and the other is the data reduction software. The AAVSO provides some options but you may wish to create your own custom software. If you submit your data to the AAVSO SID program the report format must match a pre-defined format, therefore any custom software must generate an appropriate data file.

The section below lists the software made available by the AAVSO SID program. These are available by writing the SID Analyst, and will include instructions for use.
