This is a high rank event, bright, high in the sky Alt=45 Az=255. Probably visible from home at the foot of the driveway. Centerline goes through downtown Santa Cruz. The northern limit is north of Karl so all of our Team will be inside the path. Duration = 11.3 seconds - very long. This means that it's ideal for hunting for small moons. Even a moon 1/20 of the primary in size, should be easily do-able.
Magnitude drop is 1.7, down to 13.8 magnitude.

I observed from home, got solid data under good conditions. 4x setting, Gamma=1, and used TME aperature and vertical median noise reduction in PyOTE. Note that my duration is quite solid, and 20% larger than the predicted maximum duration. This indicates either a darker colored asteroid than had been thought, or a rather oblong asteroid which presented the long axis at my chord.
