Good grazing "eclipse" of ZC 2702 Wed. evening, Oct. 17 - Updated 2007 Nov. 5, 5 pm EST
Conditions were good and the graze was observed from eight locations in and near Columbia, MD
Observations were also obtained at observatories in northern New Jersey and southern New York.
The IR weather satellite observations, which you can see for the New England area and the Mid-Atlantic region, showed that it was mostly clear along the path from southern Virginia to New Hampshire, except for a sizeable patch of clouds over northeastern Maryland and s.e. Pennsylvania up to about Perkasie. So the actual situation was much better than the last Astro Meteo forecast. It was dry in the Mid-Atlantic region, with no dewing problems, but in Massachusetts it was quite humid, and with falling temperatures, an expedition from the Clay Center in western Mass. failed due to fog that formed shortly before the graze. Conditions were quite good for our expedition in southern Columbia, MD, where we observed the graze from five stations, four video and one visual, I think all with 2 or more occultations of the star, and I think 5 at my station about 400 m north of the limit line. Farther northeast in Columbia, in a separate effort, Dale Lehman had only one occultation of the star lasting about 2 minutes, higher up (that is, farther south) on the same mountain that occulted the star for our stations the longest. Also, Andrew Scheck observed two short occultations by high mountains from his home in Scaggsville while Kevin Hartnett recorded long and short occultations from his home in Fulton. Further accounts and reports of the graze in central Maryland are listed below. Bart Huxtable in the north parking lot at Atholton High School. Andrew Scheck in Scaggsville (also included there is an account of the 3 stations that I set up in southern Columbia). Kevin Hartnett in Fulton. So far, I've heard from two others, David Nelson in High Bridge, NJ who observed the graze from the NJAA Observatory, and Frank Suits in s.e. New York. Frank had two occultations of the star and has already analyzed his 4 video-recorded events with Limovie, which you can see in his account here. With dozens of observers actually living within the path across northern Virginia and the northern Washington, DC suburbs, I'm disappointed that so far there are no reports from those areas. Maybe some reports will be sent later; it would be a shame if so many missed this convenient opportunity to observe a favorable graze. Much pre-event prediction information, maps, and plans is here.
