II) Ceres at opposition and observable Fri-Sat and Sat-Sun sunset through
12:30 am.

Ceres (530km dia) was at opposition on 8/12 and was at it's maximum
brightness of 7.6. Ceres continues at maximum brightness through 8/19.
Ceres transits at around 1AM-2Am in the morning. Ceres is low in North Am
skies . By 8/19, the Moon is sufficiently below the horizon that Ceres can
be observed without Moon light interference.

A more recent study led by Peter Thomas of Cornell University, suggests that
Ceres has a differentiated interior: observations coupled with computer
models suggest the presence of a rocky core overlain with an icy mantle.
This mantle of thickness from 120 to 60 km could contain 200 million cubic
kilometres of water, which is more than the amount of fresh water on the

Moon's diameter 3476km
