Occultation event with (4832) Palinurus, event index number 4771
Regions able to see the event: Australia
Geocentric closest approach at 2026/11/19 12:07:52 UTC
J2000 position of star is 06:10:07.7 +06:06:05
Equinox of date position of star is 06:11:34.2 +06:05:39
Star is 102 degrees from the moon. Moon is 70% illuminated.
Stellar brightness G=15.3, apparent brightess of occulting body is G=15.2
Use an exposure time of 1.00 seconds with the standard RECON-QHY system.
SNR of 7.6 per integration for unocculted signal
Expected flux drop is 47% with SNR of 3.6 for the occulted depth (per occulted point)
Apparent velocity is 12.6 km/sec on the sky relative to the star, or, 14.0 arcsec/hr.
Position angle of asteroid motion is 82.4 degrees
The recommended exposure time corresponds to 12.6 km per image.
The 1-sigma error in the time of the event is 1.0 seconds.
The 1-sigma cross-track error in the shadow position is 33.3 km.
The sky-plane scale is 3243.4 km/arcsec.
Diameter estimates:
60.0 km assuming a 5% albedo, maximum of 4.8 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.
