Does comet P/Arend-Rigaux have a large dark nucleus?The first infrared observations of the comet P/Arend-Rigaux are presented. These indicate that both the reflected solar radiation and the thermal emission from the nucleus have been detected. From the observations, a geometric albedo as low as 5 percent and an average radius of 4.8 km for the nucleus are derived.
