Occultation event with (6002) Eetion, event index number 5062
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/12/05 23:54:52 UTC
J2000 position of star is 05:47:54.0 +07:40:33
Equinox of date position of star is 05:49:21.7 +07:41:00
Star is 129 degrees from the moon. Moon is 9% illuminated.
Stellar brightness G=13.1, apparent brightess of occulting body is G=15.4
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 9.9 per integration for unocculted signal
Expected flux drop is 89% with SNR of 8.8 for the occulted depth (per occulted point)
Apparent velocity is 16.7 km/sec on the sky relative to the star, or, 20.1 arcsec/hr.
Position angle of asteroid motion is 76.0 degrees
The recommended exposure time corresponds to 2.0 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 35.6 km.
The sky-plane scale is 2996.5 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 2.8 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.1 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
