Occultation event with (2674) Pandarus, event index number 4429
Regions able to see the event: Europe
Geocentric closest approach at 2026/10/18 02:16:49 UTC
J2000 position of star is 05:02:44.0 +20:48:32
Equinox of date position of star is 05:04:19.6 +20:50:43
Star is 148 degrees from the moon. Moon is 45% illuminated.
Stellar brightness G=16.2, apparent brightess of occulting body is G=14.6
Use an exposure time of 2.00 seconds with the standard RECON-QHY system.
SNR of 4.9 per integration for unocculted signal
Expected flux drop is 19% with SNR of 0.9 for the occulted depth (per occulted point)
Apparent velocity is 6.5 km/sec on the sky relative to the star, or, 6.7 arcsec/hr.
Position angle of asteroid motion is 76.5 degrees
The recommended exposure time corresponds to 13.0 km per image.
The 1-sigma error in the time of the event is 1.6 seconds.
The 1-sigma cross-track error in the shadow position is 31.4 km.
The sky-plane scale is 3513.4 km/arcsec.
Diameter estimates:
89.9 km assuming a 5% albedo, maximum of 13.8 sec for a central chord
36.7 km assuming a 30% albedo, maximum of 5.6 sec for a central chord
Cross-track diameter of 74.3 km used for deployment plan.
