Close Approach of 2019 AV13
#7
Gold standard hell, Dennis. Based on this result you look like the platinum standard. Most impressive!!

Here's the Interactive Atlas chart showing your position & the ST4v predicted position: [attachment=2468]

When I initially did the comparison, I was using the Columbus, Ohio observing location & the positions didn't align. The predicted track was off to the southwest, but when I used the coordinates of your observing location I got the result above! The effect of parallax is significant even at 0.04 AU. The position was shifted by 6' 5" at PA 28° from the Columbus position to the Brisbane position.

I couldn't find the UCAC4 catalog in SkyTools so I used the Tycho-2 catalog plus the HIP. Normally I use the HD, Tycho-2 & GSC catalogs for the fainter stars. There are a lot to choose from.
