TARGET: SUNRISE ON ALPHONSUS' CENTRAL PEAK, 4 OCT 2011
MISSION: 55
RUKL SECTION:  Section: 42




Right on the terminator, and just below center of that line, are three craters: Ptolemaeus, Alphonsus and Arzachel.

In 1958, Russian astronomers observed strange lights in the crater Alphonsus. On November 2, 1958, the Russian astronomer Nikolai A. Kozyrey observed an apparent half-hour "eruption" that took place on the central peak of Alphonsus crater using a 48-inch (122-cm) reflector telescope equipped with a spectrometer. During this time, the obtained spectra showed evidence for bright gaseous emission bands due to the molecules C2 and C3. While exposing his second spectrogram, he noticed "a marked increase in the brightness of the central region and an unusual white colour." Then, "all of a sudden the brightness started to decrease" and the resulting spectrum was normal.

Mission 55 of over a hundred sessions was planned and executed by the colongitude and weather conditions favorable to the target site. At the time, the TCCM (Telescope & Crew Control Module) was equipped with the new SSI camera running at 400 power, providing breathtaking views with a 600 mile SIMRANGE, and 400 mile FOV. What this means is the moon is 240,000 miles from us and our scanning system took us within 600 miles of the lunar surface. We scanned the target area for an hour and a half. During the second 30-min segment the sun was coming up on Alphonsus' central peak. To watch and study this WWV-time-dubbed mission, go to

Mission researchers only viewed these missions once, so now we are asking other researchers to view them for comment and/or criticisms or other findings. In the days ahead we will be adding segment 1 and 3 to be viewed. Segment 3 includes a special treat, the rendevous with the planet Jupiter.
