Visual Magnitude Observations of the Suspected Variable Star Gaia DR3 1822800617416961152

This dataset contains visual magnitude estimates of the star Gaia DR3 1822800617416961152, suspected of variability. The brightness estimates were derived from photographic observations obtained with the Seven-Camera Astrograph of the Odessa Astronomical Observatory. Visual magnitudes were estimated using comparison stars identified in Gaia DR3.The data are provided as a time series of Julian Dates (JD) and corresponding stellar magnitudes in the photovisual magnitude system. All Julian Dates are strictly increasing and unique. The numerical precision of the original measurements is fully preserved.A colon “:” following a magnitude denotes an uncertain visual estimate, in accordance with standard variable-star observing practice. Unmarked values represent normal-confidence estimates.The dataset is intended for independent verification of variability and determination of variability parameters.
