Eclipsing Variables

Timing the minima of eclipsing binary stars.

(21 April 2022)

There are several important tasks that must be done so that the data are usable and can be combined with data from other observers. In addition to collecting the light curve data, these critical steps are needed:

Measuring the time of minimum or time of central eclipse
From the measured geocentric UT of the eclipse, determining the heliocentric UT
Reducing the photometry data to magnitudes outside the Earth's atmosphere
Produce a report in AAVSO or other formats, for archiving

Data on specific eclipsing binary stars.

Here are a few of the eclipsing binaries I've been looking at. Data for those object with dimmed names are not available yet:
