During the course of a survey for radio sources using a sea interferometer changes in the apparent intensity of the source Hydra A were observed. The intensities on two consecutive days differed by more than 30 % although the intensities of sources appearing earlier and later on the same records showed no significant changes. The position of this source given by Mills (1952) [2] is r.a. 09h 15m 46s, dec. − 11° 55′ (epoch 1950) and its I.A.U. number 09S1A.
