Summary

In the night of September 26/27, 2003 a faint 11.6 mag star TYC 0570-01150-1 will be occulted by a 100 km asteroid (709) Fringilla. This update is based on USNO/Flagstaff and TMO astrometry for the asteroid and UCAC2 star position.

The updated path shows ~4 path width south shift with time ~0.2 minutes later compared to Edwin Goffin's nominal prediction.

Updated path runs due to south shift over S Russia ~23:27.8 UT, Ukraine ~23:28.8 UT, NE Hungary ~23:29.6 UT, Slovakia ~23:29.8 UT, S Czechia and N Austria ~23:30.3 UT, S Germany ~23:30.8 UT, N France ~23:31.8 UT and NE USA ~23:41 UT. Please check the path chart for details.

Target star is the southern one in 26" wide pair and it's slightly fainter than the northern component.Clear sky and good luck !!!

The event at one glimpse: * date and approx. UT time of event: September 26, 2003 @ 23:30 UT (Europe) 23:41 UT (USA) * magnitude of target star: 11.6 * magnitude drop [mag]: 1.4 * estimated maximum duration [s]: 10.5 * path description: given above * Goffin's original chart reference: A03_0960 The occultation path: * approximate ground width [km]: 140 * uncertainty [path widths]: 0.5 * uncertainty in time [s]: 6 * map: below * remarks: Path uncertainties are given according to nominal star position errors and expected asteroid positional accuracy. Data for the target star: * name: TYC 0570-01150-1 * constellation: Pegasus * J2000 position [h,m,s; o,',"]: 22h 39m 09.9875s; +04o 03' 42.264" * position source: UCAC2 * estimated accuracy ["]: 0.03" (0.02", 0.02") * V mag [mag]: 11.63 * B-V [mag]: +1.45 * remarks: Target star is in southwest Pegasus, about 4.3 degrees north of 4.0 mag star eta Aquarii = SAO 146181. Target star is the southern one in 26" wide pair and it's slightly fainter than the northern component. Perfect for comparison. !!! 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 3.0x3.0 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.
