Nine-Years Ago Today. Visible sunspots as the sun sets over the Pacific Ocean from the Deck of the MV Odyssey. (13-Jan-2016, Semester at Sea).

Mars Occultation and Wolf Full Moon

The sky was clear, and the Wolf Full Moon rose above the trees to the east in time for the Vespera automated telescopes to be able to view Mars going behind the moon. First a time-lapse video of the Vespera telescopes observing the night sky. It stayed mostly cloud free the entire night observation session. For some of the telescopes I programed the “Plan My Night” script to observe Mars and the others to observe the Moon during the occultation event. This is because the Moon is so much brighter than Mars different image acquisition times are needed in order to see the object without it being overexposed.

The first slideshow is sequence showing the start of the Mars occultation using a Vespera Pro telescope programed to observe and track the Moon. Mars is the tiny disk on the lower left side of the moon. You can see Mars approach and then disappear behind the Moon. The Vespera telescope only records monochrome images when observing the Moon, so Mars is not red.

Slideshow of Mars going behind the Moon. Individual images can be found in my PhotoShelter Gallery.

The second slideshow is sequence showing the Mars occultation using a Vespera Pro telescope programed to observe and track Mars. Mars is the small red disk below the Moon. You can see Mars approach and then disappear behind the Moon. For the other planets Vespera telescope records a color (RGB) images so Mars is red. The image of the moon is overblown, so I reduced the saturation levels.

The third slideshow is sequence showing the end of the Mars occultation using a Vespera Pro telescope programed to observe and track the Moon. Mars is the tiny disk on the lower left side of the moon. You can see Mars approach and then disappear behind the Moon. The Vespera telescope only records monochrome images when observing the Moon, so Mars is not red.
