This is faint, but 45 degrees up, and lasts 1.0s. It's 32 deg from the moon.
Alt=45, Az=110 in Gemini, 10 deg lower right of Jupiter

I set up on the east side of Twin Gates. Used 8x setting but the star was rather marginal. But at 16x I thought it was too bright and I'd have perhaps only 2 or 3 points inside the occultation, so settled on 8x. It looked like the star was gone right at the predicted time for about a second. Clear dry calm skies.

The reference star was only a couple of arc min away from the target. |

The metric started getting worse when I progressively got more smoothed than above, which seems to indicate a low-level modulation in the opacity of the atmosphere. |

Planned to try it from "the Berm" and got an apparent ~1s occultation too. I got a 0.9375s event for 5112 T-2, 16x at the Berm.
I used small size 11 apertures because the target was very near a star of similar brightness, which I used for a reference, and size 2.4 masks.
There is a single point low drop 12 seconds before the event, but it is only a single point, and there are other single point drops almost as low throughout, so probably just noise.
