Scientific paper

The compact steep spectrum (CSS) source 1150+497 was observed with the Very Long Baseline Array (VLBA) at 5GHz and 8GHz bands. The obtained total intensity image at 5GHz shows that 1150+497 has a bright one-side jet. At 5GHz, there are 3 knots in the southwest and one knot in the northeast. At 8GHz, two knots can be modeled in the southwest. Analyzing images at 5GHz band in 3 epochs from 1982 to 2001, an estimate of separation velocity 0.478 ± 0.007 mas/year is derived as the relative motions in components A and E.
