  We present the Automated Photometry Of Transients (AutoPhOT) package, a novel
automated pipeline that is designed for rapid, publication-quality photometry
of astronomical transients. AutoPhOT is built from the ground up using Python 3
- with no dependencies on legacy software. Capabilities of AutoPhOT include
aperture and point-spread-function photometry, template subtraction, and
calculation of limiting magnitudes through artificial source injection.
AutoPhOT is also capable of calibrating photometry against either survey
catalogues, or using a custom set of local photometric standards, and is
designed primarily for ground-based optical and infrared images. We show that
both aperture and point-spread-function photometry from AutoPhOT is consistent
with commonly used software, for example DAOPHOT, and also demonstrate that
AutoPhOT can reproduce published light curves for a selection of transients
with minimal human intervention.
