Summary

In the night of September 9/10, 2003 a faint 10.4 mag star TYC 0602-00465-1 = PPM 116488 will be occulted by a 72 km asteroid (174) Phaedra. This update is based on USNO/Flagstaff astrometry for the asteroid and UCAC2 star position.

The updated path shows ~6 path width south shift with time ~0.5 minutes earlier compared to Edwin Goffin's nominal prediction.

Updated path runs due to south shift over S Russia ~19:52.5 UT, Ukraine ~19:53.4 UT, Moldavia ~19:53.9 UT, Romania ~19:54.3 UT, Serbia ~19:54.6 UT, Italy ~19:55.2 UT, Spain ~19:56.0 UT and Portugal ~19:56.3 UT. Please check the path chart for details.

Clear sky and good luck !!!

The event at one glimpse: * date and approx.

Data for the target star: * name: TYC 0602-00465-1 = PPM 116488 * constellation: Pisces * J2000 position [h,m,s; o,',"]: 00h 28m 37.6905s; +14o 36' 09.400" * position source: UCAC2 * estimated accuracy ["]: 0.03" (0.02", 0.02") * V mag [mag]: 10.4 * B-V [mag]: +0.51 * remarks: Target star is in west Pisces, about 3.8 degrees east of 2.8 mag star gamma Pegasi = SAO 91781. !!! IMPORTANT !!! Purple stars in identification chart are so called 'non-star' objects in GSC; in dense fields the 'non-stars' are often real stars or blends of close pairs. Be careful about this. Close finding chart (prepared in GUIDE8): * occulted star is in center - labeled with cross * field is 4.0x4.0 degrees * limiting magnitude is 13.0 * labeled stars have indicated SAO numbers * remarks: Second chart shows 30' blowup to show correctly the star in field.
