Flaring KeyHole USA 129, and two productive evenings
Yesterday evening at about 20:38 UTC the KeyHole USA 129 (96-072A) flared while crossing Perseus. I was observing it through the telescope at that time and noted it was bright and then faded. I cannot give an exact peak time and magnitude however, as I was concentrating on obtaining positions. I had the camera open at that time, and it catched the onset of the flare very nicely:

Here is the brightness profile:

I also captured Lacrosse 4 (00-047A) on photograph, and observed it visually. It was on time, but definitely somewhat off-track.

I tried in vain to spot the USA 193 debris pieces D and K last evening.
Finally, another picture of the KeyHole USA 129 (this time steady in brightness) shot on the evening of the 26th:
