Two-epoch VLA observations of variable galactic plane radio sources

Two-epoch VLA observations of seven variable radio sources from the galactic plane survey of Gregory and Taylor (1981) are presented. Three of the sources are found to be highly variable. They exhibit inverted spectra between 6 and 20 cm and are unresolved to 0.07-0.1 arcsec. Four other sources have morphologies reminiscent of jets and lobes and exhibit no structural changes between the two epochs. All sources contain at least one compact component, and in the case of the double and triple sources comparisons with survey data suggest that these undergo transient and dramatic changes in flux. The object GT 2203 + 559 presents the exciting possibility of another Sco X-1 candidate. Two sources have close optical counterparts. 12 references
