Occultation event with (4867) Polites, event index number 4962
Regions able to see the event: Europe
Geocentric closest approach at 2026/11/30 16:24:04 UTC
J2000 position of star is 05:30:31.8 +54:57:24
Equinox of date position of star is 05:32:45.5 +54:58:31
Star is 70 degrees from the moon. Moon is 56% illuminated.
Stellar brightness G=16.5, apparent brightess of occulting body is G=15.1
Use an exposure time of 1.15 seconds with the standard RECON-QHY system.
SNR of 3.0 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 16.5 km/sec on the sky relative to the star, or, 18.4 arcsec/hr.
Position angle of asteroid motion is 95.0 degrees
The recommended exposure time corresponds to 18.9 km per image.
The 1-sigma error in the time of the event is 0.3 seconds.
The 1-sigma cross-track error in the shadow position is 30.8 km.
The sky-plane scale is 3215.1 km/arcsec.
Diameter estimates:
62.5 km assuming a 5% albedo, maximum of 3.8 sec for a central chord
25.5 km assuming a 30% albedo, maximum of 1.6 sec for a central chord
Cross-track diameter of 57.3 km used for deployment plan.
