Hi everybody Back to observations, but having lost my reflexes.... 28888 was seen passing swiftly slightly north of mu and lambda UMa at 21h 29m 07s, so apparently still corresponding to 07159.07500452 elements. I have no more precise timing or position (I pressed my stopwatch a bit late, and here it is still late twilight).
