Search for a Frequency Shift of the 21-Centimeter Line from Taurus A near Occultation by Sun

The 21-centimeter absorption line from the direction of Taurus A was used for detection of a shift in frequency when the source passed near Sun. A possible decrease in frequency of 150 cycles per second was detected, which cannot be caused by general relativity or by the plasma around Sun.
