Notes. (a) Telescope. (b) Exposure Mid Julian date-2450000. (c) Number of exposures. (d) Total exposure time, (s). (e) Heliocentric, geocentric distance (AU), Solar phase angle, (degrees). (f)Position of the extended Sun-target radius vector (anti-solar direction) and negative of the heliocentric velocity vector (dust tail orientation) as seen in the plane of the sky measured east from the north celestial pole. (g) True anomaly, (degrees). (h) Limiting mag for non-detection, or total magnitude. (i)Inferred nucleus radius (km) assuming an albedo of 4 or 25%. (j)Magnitude through aperture diameters of 10 000, 7500, 5000, and 2500 km.
