Scientific paper

Results of infrared photometry in J, H, and K bands for 24 stellar maser sources are given. On the colour-colour diagram, nearly all the Mira variable masers are closer to the black body line than the normal M giants, which also have brighter H magnitudes. The main reason for the location of the Mira masers is the strong H2O absorption bands at 1.4 and 1.9 μm. The dust envelopes for maser sources have temperature of 600 - 700 K, so the radiation shorter than 3μm may be expected to be close to black body. The physical conditions in M supergiants are such that a peak intensity near 1 - 6 μm (the H band) may be expected.
Maser-associated Mira variables have longer periods and redder colours than normal Mira stars and M giants, suggesting greater amount of mass ejection from the central stars.
