Observations of NGC 1275 at ∼ 1396 MHz with the NRAO line interferometer in 1974 and 1976 suggest the presence of a very broad, shallow HI absorption feature centered at ∼ 5300 km sec−1. These observations were repeated in 1981 June with the Very Large Array using a greater bandwidth to determine a satisfactory baseline.
