Abstract:
    We present the results of our infrared observations of WR 140
    (=V1687 Cyg) in 2001-2010.

Description:
    The infrared photometry of WR140 (V1687 Cyg) was performed with 
    the 1.25-m telescope at the Crimean Laboratory of the Sternberg
    Astronomical Institute using a photometer with a
    liquid-nitrogen-cooled photovoltaic indium antimonide (InSb) detector.
