Announcement: New Applications
We are excited to announce the launch of our new applications! We're opening up early access to our new applications for searching, downloading, and submitting photometric observations. You can now access these applications through these links:
- • Global Data Search (new) – Search across all of AAVSO’s databases
- • Search and Download Photometric Observations – Search and export results in CSV, JSON, or XLSX
- • Submit Photometric Observations – Review your observations on a light curve with historical data
We ask for your feedback in order to help us improve these applications. Please send feedback for the applications above tofeedback@aavso.org. Note: please avoid duplicating submissions across the two submit applications.

The mission of the AAVSO is to enable anyone, anywhere to participate in scientific discovery through variable star astronomy.
