9:10 PM
There were a few low wispy clouds, but most of the sky was visible.
I recognized the following from 9:10 to 9:50:
Jupiter, the Summer Triangle, Cygnus, Lyra, Altair, Cassiopeia, and Pegasus.

9:00 PM
I saw the usual constellations, including Cygnus, Lyra, Altair, and Cassiopeia, and newer ones that I have not often observed, such as Pegasus, Andromeda, Perseus, and Aquarius.

12:00 AM
I saw Mars, Leo, and the Summer Triangle.
From 12-1 AM, I counted 7 meteors from the direction of Leo.
From 1-2 AM, I saw another 7 from Leo and 1 from a different direction.
From 2-2:45 AM, I counted 4 meteors.

APOD 2.3
Meteor between the Clouds

This is a picture of a meteor in South African skies on November 15. The meteor was likely part of the Leonid shower. This meteor shower occurs annually and originates from the Tempel-Tuttle comet in the constellation Leo. Material released from the comet is visible from Earth because the comet’s orbit intersects Earth’s. The meteor captured had a very long tail, and happened to pass between the Large and Small Magellanic Clouds, which are irregular dwarf galaxies that may orbit the Milky Way.

APOD 2.2
Young Stars in the Rho Ophiuchi Cloud
http://apod.nasa.gov/apod/
This is a picture of part of the Rho Ophiuchi cloud, a relatively close star-forming region that is in the constellation Ophiuchus. The glow is created by new stars that heat the surrounding dust; it is in the form of infrared light. Some of the stars in the region are 300,000 years old, which is very young for a star. The picture was taken from the Spitzer space telescope. This telescope was launched in 2003 and follows a heliocentric orbit, which is unusual because most space telescopes orbit Earth.

APOD 2.1
Seven Sisters Versus California
http://apod.nasa.gov/apod/ap091103.html
The Pleiades star cluster, or the Seven Sisters or M45, is a group of around 3000 stars that are about the same age; they were formed in a cloud of dust and gas. The cluster is 400 light years away and easy to see. The bluish coloring is caused by dust that reflects light from the stars. M45 is an open cluster, which means the stars are only loosely bound together by their gravitational forces. Also in this picture is the California nebula, which is not as easily visible as the Pleiades. It consists mainly of glowing hydrogen gas.
