APASS - The Latest Data Release

The AAVSO Photometric All-Sky Survey has just finished a new data release. This survey calibrates the entire sky, from 10.5mag to 16.5mag at V, and with 2.5arcsec resolution. Johnson B,V and Sloan g',r',i' filters are included. Each field is observed a minimum of 4 times on separate nights, with nightly calibrations using Landolt and SDSS standard stars. The current accuracy is 0.02mag photometry and 200mas astrometry. We have nearly completed the data acquisition for the main survey, and are starting a bright extension, measuring stars as bright as 7th magnitude and with additional u',z' and Y bandpasses. Copies of the current release can be obtained from our website or at the poster.
