Sunday morning's occultation of a 15th-magnitude star by Pluto was successfully recorded by a few amateur astronomers at locations widely separated across the path, so those observations are likely to allow a good astrometric determination of the actual occultation path, and the location of Pluto's disk relative to the star in the sky plane (and then, an accurate calculation of the actual path of the central line from which a central flash may have occurred). But so far, the observations have not been processed to determine the light variations of the star needed for this analysis; this should be accomplished in the next week or two. So far, I haven't heard how the professional astronomers fared, but I assume that several of them were successful, at least in Arizona where it was clear. Many thanks to all observers who attempted this faint but important occultation. Although several others, including myself, were clouded out, the preparations for the event were useful for testing new equipment that might be used for future occultations of faint stars. For example, with help from Bob Sandy, I made last-minute arrangements to use my Collins I3 image intensifier and Astrovid Stellacam II with the 27-inch telescope at Farpoint Observatory near Eskridge, Kansas, about 25 miles southwest of Topeka. During the day before the occultation, Gary Hug made an adaptor for the telescope that would accept the 1.25-inch-diameter cylinder of the front end of my equipment; this would be useful in any case for other equipment that they plan to run with this telescope in the future. In spite of a declination motor that broke when the telescope was first used in the evening, we were able to set the telescope about half a degree from the target star. Then, using Bob Sandy's 9-inch video monitor and a detailed star-charting program on an adjacent computer, we were able to match the video field with the pattern of stars near a 7th-mag. star, and then star hop to Pluto. An hour before the occultation, we were all set, recording the Pluto/target star combination with a good signal to noise ratio with quarter-second integrations. It would have made a nice observation, but fog rolled in about half an hour before the occultation. One of the observers at Farpoint Observatory worked with another computer there to try to record remote observations of the occultation with a remote 14-inch educational telescope in Cloudcroft, NM, but it was too cloudy to obtain any observations there. A summary of the known successful observations is in the table below.

It was clear at all locations during the occultation except at the George Observatory near Needville, west of Houston, where fog/low clouds moved in 20 min. before the occultation. The star/Pluto combination could be recorded only intermittently in breaks in the clouds. Note - we also did that at Farpoint Observatory, switching to half-second integrations, but only once was the brief clearing good enough there to see Pluto; there were other brief breaks where nearby 11th-mag. stars could be seen. Richard Keen's visual observation at Mt. Thorodin, Colo., indicated that the occultation occurred about 6 min. later than predicted, since the predicted closest approach time for his location was 10:51 UT.
