Kitt Peak Nightly Observing Program
Splendors of the Universe on YOUR Night!

Kitt Peak has an abundance of clear nights, but that doesn’t mean the clouds never move in. We hope you’ll join us again another time when our dark mountain skies are at their best!
The Green Flash
What we call “The Green Flash” is not so much a flash as a flicker of green color, seen on the top of the sun as it sets (or rises). This rare event needs just the right atmospheric conditions.
Jupiter is the largest planet in the Solar System, a “gas giant” 11 Earth-diameters across. Its atmosphere contains the Great Red Spot, a long-lived storm 2-3 times the size of the Earth. The 4 large Galilean satellites and at least 63 smaller moons orbit Jupiter.
The same side of the Moon always faces Earth because the lunar periods of rotation and revolution are the same. The surface of the moon is covered with impact craters and lava-filled basins. The Moon is about a fourth of Earth’s diameter and is about 30 Earth-diameters away.
Algieba (γ Leo)
Algieba (γ Leonis) is a binary star in the mane of Leo, the lion. These two golden-yellow giant stars are about 23 and 10 times the diameter of the Sun, and are about 130 light-years away. Their orbital period is over 500 years. In 2009, a giant planet was found orbiting one of these stars.
Spacewatch is the name of a group at the University of Arizona’s Lunar and Planetary Laboratory founded by Prof. Tom Gehrels and Dr. Robert S. McMillan in 1980. Today, Spacewatch is led by Dr. Robert S. McMillan. The original goal of Spacewatch was to explore the various populations of small objects in the solar system, and study the statistics of asteroids and comets in order to investigate the dynamical evolution of the solar system. CCD scanning studies the Main-Belt, Centaur, Trojan, Comet, Trans-Neptunian, and Earth-approaching asteroid populations. Spacewatch also found potential targets for interplanetary spacecraft missions. Spacewatch currently focuses primarily on followup astrometry of such targets, and especially follows up objects that might present a hazard to the Earth.
