OCCULTATION OF SAO 111235 BY THE ASTERIO 85 IO IS EXPECTED FROM CENTRAL ARIZONA TO S. MICHIGAN, S. ONTARIO, & LAPLAND ON SAT. EVENING, 1995 DEC. 9TH Based on observations made by R. Stone and colleagues with the U. S. Naval Observatory transit telescope at Flagstaff, Arizona, an occultation of 8.5-mag. SAO 111235 by the 157-km asteroid 85 Io will occur along a path crossing arctic western Russia (0:30 UT of December 10th UT), Lapland (0:31), Iceland (0:33), Labrador, Quebec north of Montreal and Quebec City (0:40), Ontario north of Toronto (0:41), southern Michigan (0:42), Chicago, s.e. Iowa and n.w. Missouri (0:43), Kansas, n. New Mexico (0:44), and central Arizona (in bright twilight). If you have access to a telescope of 4-inches or larger aperture that has setting circles and/or a good finder scope for locating stars this faint, you can help us measure the size and shape of this asteroid with simple visual timing techniques described below. Anyone familiar with finding variable stars and obscure comets or deep-sky objects can help with this program, and is encouraged to observe; the detail that we obtain of the asteroid's shape will be directly proportional to the number of observers who time the occultation. Please share this with other observers in your area, since this is being sent usually to only one person in each astronomical society in the target area. The path is 1.1 path widths north of that shown for this event on p. 72 of the February issue of Sky and Telescope, and the correction to the time there is 1.3 minutes late. But this could be in error by a full path- width or more. The closest approach time error should be under 2 minutes, so a five-minute observing window should be sufficient to catch the event. More astrometric observations are expected that could decrease the prediction error; note that similar observations for the January Zelinda occultation predicted the path within about 0.02", which in this case would be only 0.2 path widths, so the prediction may be more accurate than our estimate, and certainly good enough to warrant targeting mobile observers to try to fill gaps in the coverage that will be obtained from fixed-site observations. A central occultation is expected to last over 17 seconds, but it could be even longer if the asteroid is elongated in the direction of its motion. Telephone the IOTA occultation line at 301-474-4945 to find out the latest information. Some information is also posted on the IOTA asteroidal occultation page now maintained by Pickering Anomalies at URL http://www.anomalies.com. This includes Edwin Goffin's IOTA chart with a detailed finder chart locating the star south of omicron and 6 Tauri. This chart is included in the 1995 Planetary Occultation Supplement to Occultation Newsletter for North American Observers distributed to IOTA members and Occ'n Newslet. subscribers a year ago. If you don't have it, and can't download the chart from the Web site and want a copy, I can send one to you by fax tonight, if you send me your fax phone number. If you don't have that chart, or want to refer others by phone to a chart, there is also one published in the Celestial Calendars section of the December issue of Sky and Telescope. A map showing the updated path, and the area for which we want to try to coordinate coverage by mobile observers, will be posted there late this evening. A map in the form of a PostScript file can be obtained now from Lowell's WWW site, URL http://www.lowell.edu then click on Staff, then Marc Buie, and then Stellar Occultations. Even if the updated prediction shifts the path away from your fixed site, observation is valuable in case of larger-than-expected astrometric error, or for the possibility of seeing a secondary occultation by a possible satellite of Io, like the one of Ida found by the Galileo spacecraft. The map that I will produce this evening will show parallel paths that represent shifts of the asteroid's path in the sky relative to Io in increments of 0.05" or 50 "tracks", where 1 track is 0.001" in the sky or 1.9 km on the ground. Track numbers north (N) and south (S) of the nominal path will be given on the map, with distance measured perpendicular to the path (not due north or south). The asteroid is expected to be 157 km in diameter, which projects to 242 km width on the ground and which will subtend 0.127". Lines of equal time at 1-minute intervals will be labelled in U.T.; the local time of the event, on Saturday evening, December 9th Eastern time, ranges from 7:40 pm E.S.T. in Quebec to 5:44 pm M.S.T. in New Mexico and Arizona. 85 Io's magnitude will be 11.5, so there should be over a 3-mag. drop, very noticeable, if an occultation occurs. If the star is a close double, there could be a smaller drop, or step events. The B1950 position of the star is R.A. 3h 28m 21.1s, Dec. +7 deg. 01' 43" and its J2000 position is R.A. 3h 31m 01.4s, Dec. +7 deg. 11' 54". In September, IOTA members with station data in our files received local circumstance asteroidal appulse predictions that include this event, but a newer (actually, worse, relative to the star, in this case) orbit was used for that prediction than was used for the S&T map. If you have these predictions, the corrections to the new predictions are thus a little different, as follows: Subtract 0.2 minute from the time (almost right-on, certainly better than the observations); the new path is 0.29", or 2.3 diameters, or 358 km on the sky plane, north of that listed in the local circumstance predictions for your site. A table, "Station Sort", will be sent in a separate message later this evening giving the track numbers (shift from the nominal central line in units of 0.001"), Universal Time of closest approach, coordinates, and identification of over 200 stations that have a reasonable chance for seeing this occultation. You can edit it and use the "find" feature of your editor to locate stations whose names you know. By looking at the regional map described above, you can estimate the approximate track number of your location, then locate it in the station list, which is sorted by track number. If your station is not there, we would be interested in obtaining its approximate coordinates, or north-south and east-west offsets from the center of the nearest town. If possible, we would like some feedback on observing plans in your area, so we can best assess the coverage by fixed- site observers and best target mobile observers to fill in coverage gaps. If possible, practice finding the star beforehand; otherwise, allow at least an hour for this job if you don't have accurate setting circles. A form for reporting observations is given at the end of this message. In a separate message for those in the U.S.A. and Canada are map plotting coordinates for tracks at 50-track intervals [these data can be computed and supplied upon request for other regions]; they can be used to plot the track coordinates on 1:1,000,000-scale aeronautical charts available at most airports (or on other maps with latitude and longitude, such as the USGS state index or 1:250,000-scale maps available from map, engineering, or some sporting goods stores, or available for photocopying at university or college libraries). Remember that the path can shift a substantial amount to the north or south, so everyone should not pile up at the center and those outside the overall region will increase their chances of seeing the event by travelling to within it. Since this is on a Saturday evening, observers might be able to travel longer distances than usual to increase their chances for seeing the event. IOTA regional coordinators will try to plan coverage. This is being sent to ON subscribers, IOTA members, & those for whom I have e-mail addresses over a wide area, and to many others within the uncertainty zone of this event. If you are in the latter group, info. about IOTA and timing occultations is given in my articles on p. 82 of the Jan. issue and p. 72 of the Feb. issue of S&T. Those without short-wave receivers for obtaining the time signals of WWV (5 or 10 megaHertz) or CHU can calibrate watches with seconds displays by calling the U.S. Naval Observatory master clock at 1-900-410-8463, or an IOTA coordinator in your area can record WWV and a selected AM radio station that can then be used as a time standard by others. If you don't have a tape recorder, the audio of a camcorder can be used as a tape recorder. Some possible IOTA coordinators for this event are: Guy Nason, North York, Ont., phone 416-222-4814; Brad Timerson, Newark, NY, 315-331-7110; John Holtz, Coraopolis, PA, 412,262- 3452; Robert Modic, Richmond Heights, OH, 216-731-0522; Richard Walker, Davison, MI, 313-627-9524; Berton Stevens, Rolling Meadows, IL, 708-398- 0562; Walt Robinson, near Kansas City, KS, 913-422-1280; Craig McManus, Topeka, KS, 913-232-3693; MacPherson Morgan, Albuquerque, NM, 505-296-3983; and Warren Offutt, 505-682-3152. These people also can be reached by e- mail, and their e-mail addresses for your area can probably be obtained from the header of this message.

A new prediction using all transit circle data through Dec. 7 has just been issued by Larry Wasserman at Lowell. But the difference from the prediction above is negligible, being only about a second of time and 0.005" (5 tracks, or 10 km) to the north. So I will not bother to change the baseline prediction, to which any future updates will be referred. The formal error in the new result is +/-0.067" in R.A. (equivalent to an occultation time error of +/-9 seconds) and +/-0.055" in Dec. (equivalent to a path uncertainty of +/-0.43 diameters or +/-104 km perpendicular distance on the ground).
