Occultation event with (4867) Polites, event index number 4582
Regions able to see the event: Europe
Geocentric closest approach at 2026/11/06 18:25:44 UTC
J2000 position of star is 05:46:56.6 +54:06:13
Equinox of date position of star is 05:49:08.7 +54:06:41
Star is 107 degrees from the moon. Moon is 7% illuminated.
Stellar brightness G=15.4, apparent brightess of occulting body is G=15.2
Use an exposure time of 1.15 seconds with the standard RECON-QHY system.
SNR of 7.8 per integration for unocculted signal
Expected flux drop is 46% with SNR of 3.6 for the occulted depth (per occulted point)
Apparent velocity is 12.4 km/sec on the sky relative to the star, or, 13.4 arcsec/hr.
Position angle of asteroid motion is 129.1 degrees
The recommended exposure time corresponds to 14.3 km per image.
The 1-sigma error in the time of the event is 1.8 seconds.
The 1-sigma cross-track error in the shadow position is 20.7 km.
The sky-plane scale is 3332.3 km/arcsec.
Diameter estimates:
62.5 km assuming a 5% albedo, maximum of 5.0 sec for a central chord
25.5 km assuming a 30% albedo, maximum of 2.1 sec for a central chord
Cross-track diameter of 57.3 km used for deployment plan.
