Cosmos 2278 Rk fits your criteria as follows:  (for your location)

At 17:14:30 is at Az = 47, Alt = 45, or within 2 deg of Epsilon UMa.

Heads then to SE and goes into shadow at exactly 17:17:20 at Az = 102, Alt = 26.

May have gotten suddenly fainter due to tumbling?  (Not sure of the period
of this one.)

Hope this helps.
