USA 129 flaring

This evening I bagged a rich bag of objects. Amongst them was the Keyhole satellite USA 129 (96-072A), that treated me on a bright mag. -1 flare at 20;24:25 UTC (March 20) shortly after emerging from eclipse in Perseus. I captured the peak and descending brightness part on the image shown below.
