Asteroid to Occult Star on Morning of Friday, Jan. 9
This is an AstroAlert from Sky & Telescope.
This message is forwarded, with minor edits, from David Dunham of the International Occultation Timing Association.
The star is bright enough for visual observation with even small telescopes; if possible, please try to time the occultation using the techniques described at iota.jhuapl.edu/timng920.htm. With the relatively short duration, video observations are preferred, but a visual observation is much better than no observation.
Regardless of your timing method, the most important thing is to set up your telescope early enough to leave plenty of time to locate the star. You can get finder charts at several different scales to locate the star from Steve Preston's website.
You can also find an overview of the occultation path on Steve Preston's website. The path crosses Texas at 10:59 UT (4:59 am CST) with an occultation possible, considering the uncertainies, from San Antonio, Austin, Waco, and Texarkana. In Tenn., at 11:00 UT (5:00 am CST), Memphis is at the predicted n. limit and Nashville is at the expected s. limit. At 11:01 UT, an occultation is possible in Lexington, KY and Morgantown, WV. In Penn., Washington, Somerset, York, Harrisburg, Allentown, and Scranton all have a chance; the path could also cross the northernmost part of New Jersey with New York City possible but less likely. At 11:02 UT, w. and n. Conn. and Boston, Mass. have a good chance, but slightly better chances are in the predicted path just north of those places in much of Massachusetts; s. New Hamp. and southernmost Maine could also have an occultation. The path also crosses Nova Scotia, but twilight starts to get strong n.e. of Halifax. You can see the path in more detail using Derek Breit's interactive Google maps.
