Additional IMCCE stations have been added, with all of them in four groups, mainly on the south side. Okasaki's stations have been moved north to compensate, and we may want to move Earl Wilson from -70, also. According to this plan, you should select sites within +2 and -2 km of the following distances (I indicate the current Occult Watcher, or OW, station #'s that already comply with these well enough; if the separation to an adjacent station is less than 4 km, then the selected site should be within +1 and -1 km of your distance): Google map dist., km +175 Degenhardt 1 OW#63 +165 Degenhardt 2 OW#62 +155 Degenhardt 3 OW#57 +145 Degenhardt 4 OW#11 +135 Degenhardt 5 OW#55 +125 Degenhardt 6 OW#05 +120 Degenhardt 7 OW#66 +118 Degenhardt 8 OW#70 +112.14 Fleishman +110 Degenhardt 9 OW#65 +105 Degenhardt 10 OW#10 +100 Degenhardt 11 OW#59 +95 Degenhardt 12 OW#80 +92 Degenhardt 13 OW#77 +88 Degenhardt 14 OW#79 +85 Degenhardt 15 OW#01 +80 Degenhardt 16 OW#60 +75 Degenhardt 17 +70 T.

Breit's site at http://www.poyntsource.com/New/Google/20110719_23903.HTM - the OW station list, and the sites file on D. Breit's Global web site give different answers, at least at distances more than about 20 km from the central line. Observers who have selected sites are requested to send me the google map distance for their site, and I will enter that number with more precision in the list, as I've done already for several stations where this information has been reported. T. George, S. Preston, and J. Garlitz will be travelling together, and the lines that they will be covering, +40, +50, +60, and +75, will be divided between them as they determine (Preston plans to run two stations), not necessarily with the specific assigned lines that I give above. My last two stations, south of -200, are extras that I may or may not have time to set up. Similarly, Degenhardt's stations 11 - 18 are extras, but he will probably be able to set up most if not all of them. Brian Mason notes that the Hipparcos mission observations indicated that this star might not be single, but no high-resolution ground- based observations have been made to determine that. So we could end up with a shift as large as the approximate 90-km shift we had for Eudora. If that happens for Antiope, our coverage would cover one of the Antiope components completely, and the other one mostly (some 70% - 80%). Unfortunately, new observations were not able to improve the current position of ZC 3339 = HIP 112420. Meanwhile, Bill Merline has the results from his recent Keck observations, showing that the Antiope pair will be close to the French prediction, with the pair rotated about 5 deg. farther from the path motion line (a little more open) and a little closer than the French prediction. The observations show that the star is most likely single down to a little less than 0.1". Bill Owen provided 5 more positions taken last night, in addition to the three positions for Antiope taken the previous night, and there were a few new FASTT positions as well. Steve Preston computed a prediction based on these (exept for the 5 newest observations) and it moved the path an insignificant (relative to the star position uncertainty) 13 km. With the star catalog comparison using HIP1 data for the star for the nominal prediction now used on all prediction sites and by Occult Watcher, and using the orientation of the components of Antiope provided by Jerome Berthier of IMCCE on June 15, The north edge = +97 +15 (HIP2) +46 (1 sigma) = +158 km The south edge = -101 -21 (PPMXL) -46 (1sigma) = -168 km but we will continue to use +175 km for the northern end of our fence and -215 km for the southern end. The predicted zone where both components of Antiope may occult the star extends from 15 km north of center to 14 km south of it. The zone from which the expected crater on the southwestern component will occult the star (last reappearance) extends from 9 km north of center to 49 km south of it. David, dunham@starpower.net
