Variable Star Observing

The ARO observes variable stars and submits observations to the AAVSO. The focus has been to contribute to specific observing campaigns or to observe newly discovered objects or objects undergoing outburst (catacalysmic variables, etc.).

As of November 21, 2022, 27,649 observations have been submitted to the AAVSO International Database using the observer code LDJ.

In the past, it observed variable stars (mainly Cepheids and suspected Cepheids) and bright open clusters. This work was done with Daniel Majaess and David Turner of Saint Mary's University Astronomy and Physics.
