IOTA/IOTA-ES occultation update for (203) Pompeja / TYC 1885-01254-1 on January 28/29, 2003 visible from S Russia, Ukraine, N Poland, Denmark, N Scotland, NE Canada and NW USA Summary
In the night of January 28/29, 2003 a faint 11.6 mag star TYC 1885-01254-1 will be occulted by a 120 km asteroid (203) Pompeja. This update is based on USNO/Flagstaff and Geneva astrometry for the asteroid and recent UCAC star position.
The updated path shows ~1 path width north shift with time 0.5 minutes earlier compared to Edwin Goffin's nominal prediction.
Updated path runs over S Russia ~1:41.3 UT, Ukraine ~1:42.0 UT, N Poland with Warszawa in path ~1:43.0 UT, Denmark ~1:44.3 UT, N Scotland ~1:45.8 UT, NE Canada 1:53-2:00 UT and NW USA 2:00-2:05 UT. Please check the path chart for details.
Clear sky and good luck !!!
The event at one glimpse: * date and approx. UT time of event: January 29, 2003 @ 01:43 UT (Europe) 02:01 UT (Canada-US border) * magnitude of target star: 11.6 * magnitude drop [mag]: 1.6 * estimated maximum duration [s]: 19.2 * path description: given above * Goffin's original chart reference: A03_0124 The occultation path: * approximate ground width [km]: 140 * uncertainty [path widths]: 0.5 * uncertainty in time [s]: 12 * 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 1885-01254-1 * constellation: Gemini * J2000 position [h,m,s; o,',"]: 06h 09m 11.4182s; +27o 37' 29.173" * position source: recent UCAC position combined with Tycho-2 proper motion * estimated accuracy ["]: 0.04" (0.03", 0.03") * V mag [mag]: 11.63 * B-V [mag]: +1.44 * remarks: Target star is in NW Gemini, about 6.0 degrees NW of 2.9 mag star mu Geminorum = SAO 78297. Target star is brighter (southeast) component of a pair, fainter 12.3 mag star is 19" away in PA ~300 degrees. !!! 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 GUIDE7): * occulted star is in center - labeled with cross * field is 2.0x2.0 degrees * limiting magnitude is 12.5 * labeled stars have indicated SAO numbers * remarks: Second chart (with limiting mag 15.1) is enlargement to show correctly target star.
