Occultation event with (4832) Palinurus, event index number 4401
Regions able to see the event: Australia
Geocentric closest approach at 2026/10/14 19:48:33 UTC
J2000 position of star is 06:15:46.0 +06:58:53
Equinox of date position of star is 06:17:12.7 +06:58:14
Star is 148 degrees from the moon. Moon is 17% illuminated.
Stellar brightness G=14.2, apparent brightess of occulting body is G=15.5
Use an exposure time of 0.35 seconds with the standard RECON-QHY system.
SNR of 9.8 per integration for unocculted signal
Expected flux drop is 77% with SNR of 7.6 for the occulted depth (per occulted point)
Apparent velocity is 5.5 km/sec on the sky relative to the star, or, 5.6 arcsec/hr.
Position angle of asteroid motion is 151.5 degrees
The recommended exposure time corresponds to 1.9 km per image.
The 1-sigma error in the time of the event is 4.8 seconds.
The 1-sigma cross-track error in the shadow position is 23.4 km.
The sky-plane scale is 3530.6 km/arcsec.
Diameter estimates:
60.0 km assuming a 5% albedo, maximum of 11.0 sec for a central chord
24.5 km assuming a 30% albedo, maximum of 4.5 sec for a central chord
Cross-track diameter of 52.1 km used for deployment plan.
