The event at one glimpse: * date and approx. UT time of event: December 15, 2002 @ 18:56 UT (Japan) 19:02 UT (Europe) * magnitude of target star: 9.1 * magnitude drop [mag]: 1.2 * estimated maximum duration [s]: 40 * path description: given above The occultation path: * approximate ground width [km]: 1280 * uncertainty [path widths]: 1 (?) * uncertainty in time [s]: 40 (?) * map: below * remarks: Path uncertainties are given according to nominal star position errors and expected satellite positional accuracy. Data for the target star: * name: TYC 1310-02435-1 * constellation: Taurus * J2000 position [h,m,s; o,',"]: 05h 41m 33.8869s; +22o 03' 31.208" * position source: Tycho-2 * estimated accuracy ["]: 0.05" (0.03", 0.03") * V mag [mag]: 9.12 * B-V [mag]: +1.04 * remarks: Target star is in Taurus, only 1.3 degrees NE of 3.0 mag star zeta Tauri = SAO 77336 (lower horn of Taurus). !!! 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 3.4x2.5 arcminutes * limiting magnitude is 15.0 * labeled stars have indicated SAO numbers * remarks: Click here for the same image but overlayed over DSS-2.

Data for the event: * UT date and time of least geocentric approach: 18:59:03 UT * approx. V mag of minor planet at event [mag]: 9.9 * geocentric parallax of satellite ["]: 1.092 * magnitude drop [mag]: 1.2 * estimated maximum duration [s]: 40 * remarks: Calculator(s): Jan Manek
