There was, but I watched it 1-power while walking home from the bus,
having found a small grove that protected me from streetlights.

I had the following predictions:             Angle  Mag  Estimate
45 98- 3-19 19:47:50.0 085 52 11h48  44.7  R  2.96  1.1     2.5
48 98- 3-19 19:47:55.0 084 52 11h52  45.1  R  3.32  1.4     3
24 98- 3-19 19:48:55.0 084 53 11h47  46.0  R  2.18  0.1     1

46 98- 3-19 19:57:00.0 088 60 11h19  48.8  R  3.61  1.6     3

29 98- 3-19 21:03:39.5 040 24 17h19  44.7  R  1.19 -0.6    -1

Ir45+48 sailed about three degrees apart through the handle of Big Dipper
and Ir 24 appeared there just when I lost the first two in lower UMa.
Ir24 had its maximum 5 degrees before the predicted position, faded
about one magnitude, then brightened a few tenths at the predicted place.

Two minutes before Ir 45 I saw a mag.2 object on a parallell path,
about two degrees lower.
