Occultation event with (2674) Pandarus, event index number 1122
Regions able to see the event: SAfrica
Geocentric closest approach at 2025/07/10 02:07:35 UTC
J2000 position of star is 02:47:06.2 +15:04:15
Equinox of date position of star is 02:48:30.8 +15:10:36
Star is 125 degrees from the moon. Moon is 99% illuminated.
Stellar brightness G=12.9, apparent brightess of occulting body is G=15.2
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 12.0 per integration for unocculted signal
Expected flux drop is 89% with SNR of 10.7 for the occulted depth (per occulted point)
Apparent velocity is 24.9 km/sec on the sky relative to the star, or, 20.9 arcsec/hr.
The recommended exposure time corresponds to 3.0 km per image.
The 1-sigma error in the time of the event is 1.5 seconds.
The 1-sigma cross-track error in the shadow position is 13.9 km.
The sky-plane scale is 4297.0 km/arcsec.
Diameter estimates:
89.9 km assuming a 5% albedo, aximum of 3.6 sec for a central chord
36.7 km assuming a 30% albedo, maximum of 1.5 sec for a central chord
Cross-track diameter of 89.9 km used for deployment plan.
