Diurnal Parallax Distances for Near-Sun Objects from the Geostationary Coronagraph GOES-19/CCOR-1

Geostationary motion provides a repeating observer baseline that can encode target range in coronagraph images. We apply this to GOES-19/CCOR-1 by registering each frame to field stars and fitting the fixed-phase sidereal-day parallax jointly with smooth sky motion. Thirteen known-distance tracks of planets, asteroids,...
