The eclipsing binary 44i Bootis, the fainter component of the visual binary ADS 9494, has been observed during 1980 as well as during 1988. The observations were made with the 48-inch Cassegrain reflector at the Kryonerion Station of the National Observatory of Athens, Greece. The individual observations of 44i Bootis are presented for years 1980 and 1988 and are also discussed. A linear as well as a quadratic least square fitting to the O-C diagram of 44i Boo for the last decade is given in which it is shown that the period of the system continues to increase.
