Occultation event with (4832) Palinurus, event index number 4786
Regions able to see the event: Australia
Geocentric closest approach at 2026/11/20 15:57:27 UTC
J2000 position of star is 06:09:41.4 +06:05:15
Equinox of date position of star is 06:11:07.9 +06:04:51
Star is 88 degrees from the moon. Moon is 80% illuminated.
Stellar brightness G=13.6, apparent brightess of occulting body is G=15.2
Use an exposure time of 0.19 seconds with the standard RECON-QHY system.
SNR of 9.7 per integration for unocculted signal
Expected flux drop is 81% with SNR of 7.9 for the occulted depth (per occulted point)
Apparent velocity is 13.0 km/sec on the sky relative to the star, or, 14.4 arcsec/hr.
Position angle of asteroid motion is 83.2 degrees
The recommended exposure time corresponds to 2.5 km per image.
The 1-sigma error in the time of the event is 0.9 seconds.
The 1-sigma cross-track error in the shadow position is 33.4 km.
The sky-plane scale is 3237.0 km/arcsec.
Diameter estimates:
60.0 km assuming a 5% albedo, maximum of 4.6 sec for a central chord
24.5 km assuming a 30% albedo, maximum of 1.9 sec for a central chord
Cross-track diameter of 52.1 km used for deployment plan.
