IOTA/IOTA-ES occultation update for
(1032) Pafuri / HIP 48303 = SAO 81044 on November 7/8, 2005
visible from England, Denmark, S Sweden, Estonia and N Russia
Summary
In the morning of night of November 7/8, 2005 a bright 8.7 mag star HIP 48303 = SAO 81044 will be occulted by a 59 km asteroid (1032) Pafuri. This update is based on USNO/Flagstaff and TMO astrometry for the asteroid and UCAC2 star position.
The updated path shows ~10 path width north shift with time ~0.8 minutes later compared to Edwin Goffin's nominal prediction.
Updated path runs over England ~1:32.0 UT, Denmark ~1:32.4 UT, S Sweden ~1:32.6 UT, Estonia ~1:33.2 UT and N Russia ~1:33.3-1:36 UT. Please check the path chart for details.

Finding charts (prepared in GUIDE8):
* occulted star is in center - labeled with cross
* labeled stars have indicated SAO numbers
* (smaller) square box shows 30' field in all wider field charts
* (larger) square box shows 3° field in wide field charts
* remarks:
Target star is in NW Leo, about 3.2 degrees SSE of epsilon Leonis = SAO 81004.
!!! 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.
