Occultation event with (4832) Palinurus, event index number 4878
Regions able to see the event: Australia
Geocentric closest approach at 2026/11/25 12:02:30 UTC
J2000 position of star is 06:07:43.3 +06:02:36
Equinox of date position of star is 06:09:09.9 +06:02:16
Star is 27 degrees from the moon. Moon is 99% illuminated.
Stellar brightness G=15.5, apparent brightess of occulting body is G=15.1
Use an exposure time of 0.90 seconds with the standard RECON-QHY system.
SNR of 6.5 per integration for unocculted signal
Expected flux drop is 43% with SNR of 2.8 for the occulted depth (per occulted point)
Apparent velocity is 14.3 km/sec on the sky relative to the star, or, 16.0 arcsec/hr.
Position angle of asteroid motion is 86.4 degrees
The recommended exposure time corresponds to 12.9 km per image.
The 1-sigma error in the time of the event is 0.7 seconds.
The 1-sigma cross-track error in the shadow position is 34.2 km.
The sky-plane scale is 3212.6 km/arcsec.
Diameter estimates:
60.0 km assuming a 5% albedo, maximum of 4.2 sec for a central chord
24.5 km assuming a 30% albedo, maximum of 1.7 sec for a central chord
Cross-track diameter of 52.1 km used for deployment plan.
