    I have started data mining on an extensive collection of images which contain a star included in the BAA-VSS photometry database. Each of those images also contain a large number of field stars, from dozens to thousands, and it is within these where I am searching.

    Just one example: in the field of FS And is Gaia DR3 381889186083910272. My database contains the following records:

    name | jd | mag | err
    —————————-+—————-+———–+———-
    Gaia DR3 381889186083910272 | 2458457.473449 | 15.86404 | 0.010823
    Gaia DR3 381889186083910272 | 2458817.423843 | 16.219902 | 0.007154
    Gaia DR3 381889186083910272 | 2458846.468642 | 16.567724 | 0.00524
    Gaia DR3 381889186083910272 | 2458869.395041 | 16.400318 | 0.014646
    Gaia DR3 381889186083910272 | 2458873.411961 | 16.414312 | 0.017559
    Gaia DR3 381889186083910272 | 2459447.481782 | 14.537961 | 0.01448

    This is an abridged version, the database itself contains more information.

    It is fairly clearly variable but six points do not make a light curve sufficient to characterize the type of variable.

    How and to whom should this information be reported?

    I’ll ask on the relevant AAVSO forum as well.

    Paul
