Occultation event with (4832) Palinurus, event index number 4674
Regions able to see the event: Europe
Geocentric closest approach at 2026/11/13 20:40:06 UTC
J2000 position of star is 06:12:03.6 +06:11:06
Equinox of date position of star is 06:13:30.1 +06:10:36
Star is 158 degrees from the moon. Moon is 18% illuminated.
Stellar brightness G=16.7, apparent brightess of occulting body is G=15.3
Use an exposure time of 1.55 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 21% with SNR of 0.6 for the occulted depth (per occulted point)
Apparent velocity is 10.8 km/sec on the sky relative to the star, or, 11.9 arcsec/hr.
Position angle of asteroid motion is 77.4 degrees
The recommended exposure time corresponds to 16.8 km per image.
The 1-sigma error in the time of the event is 1.5 seconds.
The 1-sigma cross-track error in the shadow position is 32.6 km.
The sky-plane scale is 3278.0 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 2.3 sec for a central chord
Cross-track diameter of 52.1 km used for deployment plan.
