Popis:	Our observations of Comet C/2004 Q2 (Machholz) in the range from 1.2 to 4.8 µm indicate that the material outflowed from the cometary surface in the form of fragments that separated into gas and dust under sublimation on time scales of the order of days. The albedo of these fragments in the range under study was wavelength independent, while the dust was heated by the Sun to an equilibrium temperature at a cross section Qλ inversely proportional to the wavelength.
