Occultation event with (6002) Eetion, event index number 4714
Regions able to see the event: SMexico
Geocentric closest approach at 2026/11/16 06:49:53 UTC
J2000 position of star is 05:56:51.9 +08:29:12
Equinox of date position of star is 05:58:19.9 +08:29:18
Star is 136 degrees from the moon. Moon is 39% illuminated.
Stellar brightness G=16.5, apparent brightess of occulting body is G=15.6
Use an exposure time of 1.05 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 30% with SNR of 0.9 for the occulted depth (per occulted point)
Apparent velocity is 13.2 km/sec on the sky relative to the star, or, 15.4 arcsec/hr.
Position angle of asteroid motion is 61.7 degrees
The recommended exposure time corresponds to 13.8 km per image.
The 1-sigma error in the time of the event is 1.0 seconds.
The 1-sigma cross-track error in the shadow position is 33.4 km.
The sky-plane scale is 3074.5 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 3.5 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.4 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
