Using WWV and SkyMap, both these reference points were exactly as predicted (+/- 0.5 sec). The magnitude seemed to be unsteady, occasionally becoming invisible (although it passed only about 12-15 degrees below the Moon which could have caused some false variance). When it split the two stars in Virgo (one star mag 6.0 and the other mag 6.4) SkyMap predicted 99099A to be mag 6.3 and I'd say, comparing to the two stars, that 6.3 was about right.
