Thank you for taking the time to fill out the Chart Error Reporting Form. Your information will be used to evaluate, prioritize and make the appropriate corrections to errors found on AAVSO variable star charts.

First Things First
Please access the AAVSO Variable Star Plotter and verify that you are using the most recent version of the chart before reporting an error.

Then, check to see that no one has reported the error already.
