Occultation event with (2674) Pandarus, event index number 3904
Regions able to see the event: Australia
Geocentric closest approach at 2026/07/29 18:33:28 UTC
J2000 position of star is 04:39:17.3 +20:37:07
Equinox of date position of star is 04:40:51.6 +20:40:09
Star is 123 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=16.1, apparent brightess of occulting body is G=15.2
Use an exposure time of 0.70 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 29% with SNR of 0.9 for the occulted depth (per occulted point)
Apparent velocity is 28.8 km/sec on the sky relative to the star, or, 23.6 arcsec/hr.
Position angle of asteroid motion is 83.6 degrees
The recommended exposure time corresponds to 20.1 km per image.
The 1-sigma error in the time of the event is 0.3 seconds.
The 1-sigma cross-track error in the shadow position is 31.2 km.
The sky-plane scale is 4384.0 km/arcsec.
Diameter estimates:
89.9 km assuming a 5% albedo, maximum of 3.1 sec for a central chord
36.7 km assuming a 30% albedo, maximum of 1.3 sec for a central chord
Cross-track diameter of 74.3 km used for deployment plan.
