VPHOT is an excellent online tool for doing photometric analysis of FITS image data. SSON and the people who created VPHOT worked together to enable SSON customers to have their SSON data sent directly to their VPHOT account directory, which is provided to by the AAVSO. Please visit their website at http://www.aavso.org/vphot.

Below is the process to send your data to VPHOT:

1. You must be an AAVSO member and be prepared to enter your VPHOT username.
   
2. At the bottom of the SUBMIT JOB section of the Observation Request Form there is a new check box you can click on and check to have your SSON data automatically sent to your VPHOT account. Click the check box and enter your VPHOT username in the field to the right of the check box.
   
3. Submit your SSON schedule by clicking the Submit Schedule button to enter your jobs in the SSON observing queue.
   
4. When your SSON jobs are processed at the end of the observing run, your FITS files are transferred to your SSON FTP directory where you can download them. In addition, your files will also be transferred to your VPHOT account for you to process with VPHOT.
