There were several additional timings made. This interesting sequence is part of a composite series of video observations I made at a site in Mexico along with Chuck Herold and Richard Nugent who manned other stations. The site position was initially determined using one GPS receiver in 1993 but the information was not accurate enough. I had to resurvey it again in May 2000 to obtain a more precise geodetic position. When combined with other observations made in Canada of the same stellar occultation, it is hoped an improved lunar polar diameter may be determined.
Occultations involve other bodies as well.
Here are two frames of video I shot at the Mexico City airport depicting Venus as it is emerging after being occulted by the moon some years ago. In the first photo, Venus is partially emerged from behind the dark limb of the moon. In the next frame, Venus is fully emerged. Note the edge of the sunlit moon just to the lower right. We presented the above examples of occultation phenomena in the hopes that readers of this page will be stimulated to enter this interesting field that offers such potential for contribution and discovery.
