Applications of the AAVSO Photometric All-Sky Survey (APASS) to observations of objects in our Solar System

The AAVSO Photometric All-Sky Survey (APASS) is designed to provide photometric standards over the entire sky in the magnitude range 6.5 < V < 17.5mag in B, V, u, g, r, i, z and Y filter passbands. For the magnitude range, APASS is well matched to optical telescopes from 8-cm up to 2- to 3-meters in diameter. The survey was originally conceived to facilitate variable star observations. However, having photometric standards in every image taken can be of great utility to the Solar System community as well. Not only does this make it easier to combine extended time series photometry of observations of objects like asteroid and comets that move appreciably, it also makes it possible to recover photometry at the few percent level for data taken under non-photometric conditions (e.g. as demonstrated with SDSS data by Ivezic et al 2007, AJ, 134, 973). APASS data have been taken between 2010 and 2018 with twin ASA 20-cm astrographs installed at northern and southern hemisphere sites. Over the course of the survey, we have accummulated over 500,000 images, each 2.8 x 2.8 degrees in size. We present initial results of our work to compile a catalogue of all the serendipitous observations of asteroids and comets in those images. For the bulk of the survey data, we have contemporaneous five color (B,V,g,r,i) imaging.
