Occultation event with (4832) Palinurus, event index number 4626
Regions able to see the event: SAfrica
Geocentric closest approach at 2026/11/10 01:34:59 UTC
J2000 position of star is 06:13:09.4 +06:15:25
Equinox of date position of star is 06:14:35.9 +06:14:53
Star is 137 degrees from the moon. Moon is 1% illuminated.
Stellar brightness G=16.3, apparent brightess of occulting body is G=15.3
Use an exposure time of 1.35 seconds with the standard RECON-QHY system.
SNR of 4.1 per integration for unocculted signal
Expected flux drop is 28% with SNR of 1.2 for the occulted depth (per occulted point)
Apparent velocity is 9.5 km/sec on the sky relative to the star, or, 10.4 arcsec/hr.
Position angle of asteroid motion is 73.0 degrees
The recommended exposure time corresponds to 12.9 km per image.
The 1-sigma error in the time of the event is 1.9 seconds.
The 1-sigma cross-track error in the shadow position is 31.4 km.
The sky-plane scale is 3304.1 km/arcsec.
Diameter estimates:
60.0 km assuming a 5% albedo, maximum of 6.3 sec for a central chord
24.5 km assuming a 30% albedo, maximum of 2.6 sec for a central chord
Cross-track diameter of 52.1 km used for deployment plan.
