Occultation event with (6002) Eetion, event index number 5086
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/12/07 04:03:58 UTC
J2000 position of star is 05:47:17.0 +07:38:18
Equinox of date position of star is 05:48:44.6 +07:38:47
Star is 142 degrees from the moon. Moon is 3% illuminated.
Stellar brightness G=16.0, apparent brightess of occulting body is G=15.3
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 35% with SNR of 1.1 for the occulted depth (per occulted point)
Apparent velocity is 16.8 km/sec on the sky relative to the star, or, 20.2 arcsec/hr.
Position angle of asteroid motion is 76.6 degrees
The recommended exposure time corresponds to 10.1 km per image.
The 1-sigma error in the time of the event is 0.2 seconds.
The 1-sigma cross-track error in the shadow position is 36.1 km.
The sky-plane scale is 2994.3 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 2.7 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.
