Mosaic of the visible-light images of 324P (at the center of each panel). All images are in the R band, except for two PS1 images on 2010 June 26 in the z band, and on 2010 September 8 in the g band. All panels show the north (N), the east (E), the antisolar direction (−⊙) and the negative heliocentric velocity vector (−υ), as projected on the sky. Panels are labeled with dates of observation in UT YYYY-MM-DD format, and employed telescope. The label PS1 refers to the Panoramic Survey Telescope and Rapid Response System PanSTARRS (PS1) telescope, equipped with the GPC1 instrument; INT to the Isaac Newton Telescope, equipped with the WFC instrument; GN to the Gemini Multi-Object Spectrograph North, equipped with the Gemini Multi-Object Spectrograph North (GMOS-N) instrument; NTT to the New Technology Telescope, equipped with the ESO Faint Object Spectrograph and Camera (EFOSC) instrument; VLT to the Very Large Telescope, equipped with the FOcal Reducer and low dispersion Spectrograph 2 (FORS2) instrument; CFHT to the Canada-France-Hawaii Telescope, equipped with the MegaPrime instrument; LDT to the Lowell Discovery Telescope, equipped with the Large Monolithic Images (LMI) instrument; and GS to the Gemini Multi-Object Spectrograph South, equipped with the Gemini Multi-Object Spectrograph South (GMOS-S) instrument.
