271P/van Houten–Lemmon (previously P/1960 S1 and P/2012 TB36) is a short-period comet discovered in 1966 by Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld on eight Palomar plates taken by Tom Gehrels between 24 September and 26 October 1960 as a hazy object of 17th magnitude. It was considered lost and designated D/1960 S1 until recovered by the Mount Lemmon Survey on 17 September 2012.[4]
