An object originally reported as stellar by NEAT and LONEOS and named 2003 SQ215 was found to show a coma by Alan Fitzsimmons et al. The period is nearly 13 years and it reached perihelion at 2.30 au in late March 2004. An apparently asteroidal object reported independently by the NEAT 24 September 2003 and LONEOS on 27 September was subsequently found to show a nonstellar appearance in individual 30-s R-band images taken by A. Fitzsimmons and C. Snodgrass, Queen's University of Belfast, and O. Hainaut, European Southern Observatory (ESO), in January 2004. A 20th magnitude comet was discovered in PanSTARRS 1 images taken with the 1.8m Ritchey- Chretien on 12 August 2016. Michael Meyer and Gareth Williams identified it with 2003 SQ215, and also found earlier PanSTARRS and Crni Vrh images.
