Occultation event with (4867) Polites, event index number 4636
Regions able to see the event: Europe
Geocentric closest approach at 2026/11/10 17:38:10 UTC
J2000 position of star is 05:44:54.2 +54:18:58
Equinox of date position of star is 05:47:06.7 +54:19:31
Star is 146 degrees from the moon. Moon is 2% illuminated.
Stellar brightness G=16.6, apparent brightess of occulting body is G=15.2
Use an exposure time of 1.25 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 22% with SNR of 0.7 for the occulted depth (per occulted point)
Apparent velocity is 13.1 km/sec on the sky relative to the star, or, 14.3 arcsec/hr.
Position angle of asteroid motion is 122.1 degrees
The recommended exposure time corresponds to 16.4 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 23.4 km.
The sky-plane scale is 3306.5 km/arcsec.
Diameter estimates:
62.5 km assuming a 5% albedo, maximum of 4.8 sec for a central chord
25.5 km assuming a 30% albedo, maximum of 1.9 sec for a central chord
Cross-track diameter of 57.3 km used for deployment plan.
