Single-epoch VLA observations at 20 and 6 cm are reported for 12 variable and possibly variable sources having variability time scales of a few days, that were discovered during a survey of the galactic plane for variable emission. The sources exhibit a wide range of arcsecond scale structure, including single-point sources, multiple-component emission, and asymmetric jetlike structure. Galactic or extragalactic origin cannot be distinguished based on these results alone. The structures seen are found among both extragalactic sources and some galactic variables such as Sco X-1 and SS 433. No optical counterparts were found to the plate limit of the Palomar Sky Survey. Thus, in all cases, these sources are probably at distances greater than a few kpc. A number of observational programs to discriminate between galactic and extragalactic origin are suggested.
