The comet was discovered by Alexandre Schaumasse during a visual search with the 400mm coude equatorial at Nice, France in December 1911 as a 12m diffuse object and it reaches a similar magnitude at average returns. The 1952 return was very favourable and the comet reached 5m, though there may have been an outburst.Date10x10 magErrorKphot magComa '29-Aug-1717.390.0714.30.222-Sep-1715.980.0112.90.715-Dec-1714.700.0811.53.715-Feb-1816.760.0113.70.413-Mar-1817.290.0314.20.523-Mar-1817.600.0815.30.416-Apr-1817.810.0214.70.3
