Infrared observations of He2-442 carried out at Crimean Station of Sternberg Institute during 1984–1986 revealed that in the past ten years the 1–10 μm flux has decreased by factor ∼ 2.4, the colour temperature determined from (K-L) index has decreased by ∼ 300 K, and the infrared energy distribution has been changed also essentially. However, the definite cool star features, for example, Mira-like variability was not yet recorded.
