Occultation event with (4832) Palinurus, event index number 4678
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/14 04:34:16 UTC
J2000 position of star is 06:11:57.4 +06:10:47
Equinox of date position of star is 06:13:23.9 +06:10:17
Star is 156 degrees from the moon. Moon is 21% illuminated.
Stellar brightness G=14.6, apparent brightess of occulting body is G=15.3
Use an exposure time of 0.55 seconds with the standard RECON-QHY system.
SNR of 9.6 per integration for unocculted signal
Expected flux drop is 65% with SNR of 6.2 for the occulted depth (per occulted point)
Apparent velocity is 10.9 km/sec on the sky relative to the star, or, 12.0 arcsec/hr.
Position angle of asteroid motion is 77.7 degrees
The recommended exposure time corresponds to 6.0 km per image.
The 1-sigma error in the time of the event is 1.4 seconds.
The 1-sigma cross-track error in the shadow position is 32.4 km.
The sky-plane scale is 3275.9 km/arcsec.
Diameter estimates:
60.0 km assuming a 5% albedo, maximum of 5.5 sec for a central chord
24.5 km assuming a 30% albedo, maximum of 2.2 sec for a central chord
Cross-track diameter of 52.1 km used for deployment plan.
