  Recent research suggests a correlation between the variability and intrinsic
brightness of quasars. If calibrated, this could lead to the use of quasars on
the cosmic distance ladder, but this work is currently limited by lack of
quasar light curve data with high cadence and precision. The Python photometric
data pipeline SunPhot is being developed as part of preparations for an
upcoming quasar variability survey with the International Liquid Mirror
Telescope (ILMT). SunPhot uses aperture photometry to directly extract light
curves for a catalogue of sources from calibrated ILMT images. SunPhot v.2.1 is
operational, but the project is awaiting completion of ILMT commissioning.
