UVOT observations of Comet Lulin. A) 2009-01-28, uvw1. B) image A divided by coma profile. C) 2009-02-16, uvw1. D) 2009-02-16, v-band. E) image D with the coma profile subtracted. F) 2009-03-04, uvw1. G) 2009-03-04, v-band. All images are oriented in the same way (east left, north up) and have the same angular scale (UVOT’s FOV is 17 × 17 arcmin). Iso-intensity contours are shown on a logarithmic scale to enhance fainter features. In panel F) the solar direction vector and the orbital vector are coincident.
