Abstract The mean period of 1K Tauri, a very cool Mira variable, has been found to be 470 j 5 days on the basis of 8 years of photometric observations in the 1- region. Its mean amplitude of 2.7 mag in 1(104) is the largest known among Miras. The spectral type consistently reaches M10 at minimum light and has not been observed earlier than M8.1 at maximum. It is pointed out that, in the case of a Mira variable observed in only two consecutive cycles, a better estimate of the mean period can be obtained from the interval between successive maxima than from the interval between recurrences of the same magnitude.
