1 This is the Data and some Graphs for the time of the lunar eclipse of Feb 20-21 2008   The set up was a stationary one with the Laser in the east at about 170 degrees azimuth and elevated about 45 degrees above the horizon. The eclipse happened to the south of the veladors direction, and above its direction. the camera was in the west. The beam size was 2 meters. The time of the mid totality was 2226 by the united states navel observatory. Local time was not figured into this time but from the data it seems to appear. At the time the earth moon and sun are in as straight a line as possible and thus the effect of the sun and moon are opposite in direction giving the earth as little motion as possible from these 2 bodies. The moon moves to the east from the earths perspective and the sun at this time is also moving east due to earths rotation. I do not know the actual motion of the earth to the sun but it is moving away as early Jan. was the closest approach ie perihelion. The times of the pictures was by a wristwatch and accurate to 1-2 minutes as the atomic clock was busy resetting itself. The temperature was 64 degrees F.
