Finding Longitudinal Data of Star Magnitudes in Surveys

Click For Summary
SUMMARY

This discussion focuses on identifying sky surveys that provide longitudinal data of star magnitudes, emphasizing the need for surveys with multiple observations over time. Key surveys mentioned include the AAVSO catalogue, OGLE, TASS, ASAS, and NSVS, all of which meet the criteria of periodic observations. The user seeks additional recommendations for surveys with public data access, highlighting the importance of consistent observation over mere single-phase imaging.

PREREQUISITES
  • Understanding of astronomical surveys and their methodologies.
  • Familiarity with the AAVSO catalogue and its significance in variable star observation.
  • Knowledge of the OGLE project and its contributions to astrophysics.
  • Basic skills in data retrieval from online astronomical databases.
NEXT STEPS
  • Research additional sky surveys with longitudinal data, such as the Kepler Space Telescope data.
  • Explore the capabilities of the Vizier service for accessing astronomical catalogues.
  • Investigate the data analysis techniques used in variable star research.
  • Learn about the methodologies employed in the TASS and ASAS surveys for star magnitude monitoring.
USEFUL FOR

Astronomers, astrophysics researchers, and data scientists interested in variable star observation and analysis of longitudinal astronomical data.

I am trying to find some sky surveys that have longitudinal data of star magnitudes. The passband does not matter. All that matters is that stars has been observed periodically for a decent amount of time (no surveys with only 9-10 observations per catalogue object).
Sadly, the only ones I know of thus far are:
AAVSO catalogue (American Association of Variable Star Observers)
OGLE (Optical Gravitational Lensing Experiment)
TASS (The Amateur Sky Survey)
ASAS (All Sky Automated Survey)
NSVS (Northern Sky Variability Survey)

The other surveys I find tend to image each region of the sky only once per survey phase.

Can anyone recommend any other surveys which have public data access online?

Thank you in advance!
