Occultation event with (2674) Pandarus, event index number 4827
Regions able to see the event: SMexico
Geocentric closest approach at 2026/11/23 03:39:48 UTC
J2000 position of star is 04:48:57.4 +20:17:06
Equinox of date position of star is 04:50:32.8 +20:19:48
Star is 34 degrees from the moon. Moon is 97% illuminated.
Stellar brightness G=16.6, apparent brightess of occulting body is G=14.2
Use an exposure time of 1.75 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 10% with SNR of 0.3 for the occulted depth (per occulted point)
Apparent velocity is 17.1 km/sec on the sky relative to the star, or, 18.8 arcsec/hr.
Position angle of asteroid motion is 81.9 degrees
The recommended exposure time corresponds to 30.0 km per image.
The 1-sigma error in the time of the event is 0.5 seconds.
The 1-sigma cross-track error in the shadow position is 31.5 km.
The sky-plane scale is 3289.0 km/arcsec.
Diameter estimates:
89.9 km assuming a 5% albedo, maximum of 5.2 sec for a central chord
36.7 km assuming a 30% albedo, maximum of 2.1 sec for a central chord
Cross-track diameter of 74.3 km used for deployment plan.
