At the urging of Mark Kidger, I fought Astrometrica into submission to measure a position for Thebe.

At 22:24:23 UT Thebe was measured to be at 19:23:44.099 -22:25:14.62 with a formal error of 0.09 arcsec in each coordinate. The systematic errors arising from the difficulty of placing the centroid by eye are probably 2 or 3 times that.

There is no significant difference from the position predicted by the JPL.
