Occultation event with (2674) Pandarus, event index number 1098
Regions able to see the event: SAmericaS
Geocentric closest approach at 2025/06/27 09:10:03 UTC
J2000 position of star is 02:39:31.5 +14:32:44
Equinox of date position of star is 02:40:55.6 +14:39:15
Star is 80 degrees from the moon. Moon is 5% illuminated.
Stellar brightness G=15.0, apparent brightess of occulting body is G=15.2
Use an exposure time of 0.75 seconds with the standard RECON-QHY system.
SNR of 8.6 per integration for unocculted signal
Expected flux drop is 55% with SNR of 4.7 for the occulted depth (per occulted point)
Apparent velocity is 29.5 km/sec on the sky relative to the star, or, 24.0 arcsec/hr.
The recommended exposure time corresponds to 22.1 km per image.
The 1-sigma error in the time of the event is 1.3 seconds.
The 1-sigma cross-track error in the shadow position is 14.2 km.
The sky-plane scale is 4419.2 km/arcsec.
Diameter estimates:
89.9 km assuming a 5% albedo, aximum of 3.0 sec for a central chord
36.7 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 89.9 km used for deployment plan.
