Occultation event with (6002) Eetion, event index number 4782
Regions able to see the event: SAmericaN,SAmericaS
Geocentric closest approach at 2026/11/20 07:19:36 UTC
J2000 position of star is 05:55:18.5 +08:17:48
Equinox of date position of star is 05:56:46.4 +08:17:58
Star is 89 degrees from the moon. Moon is 77% illuminated.
Stellar brightness G=16.3, apparent brightess of occulting body is G=15.5
Use an exposure time of 0.85 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 33% with SNR of 1.0 for the occulted depth (per occulted point)
Apparent velocity is 14.1 km/sec on the sky relative to the star, or, 16.6 arcsec/hr.
Position angle of asteroid motion is 65.5 degrees
The recommended exposure time corresponds to 12.0 km per image.
The 1-sigma error in the time of the event is 0.8 seconds.
The 1-sigma cross-track error in the shadow position is 33.9 km.
The sky-plane scale is 3052.5 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 3.3 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.3 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
