Occultation event with (6002) Eetion, event index number 3100
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/01/03 02:00:24 UTC
J2000 position of star is 02:53:48.0 +08:56:08
Equinox of date position of star is 02:55:11.8 +09:02:25
Star is 56 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=16.6, apparent brightess of occulting body is G=15.6
Use an exposure time of 2.00 seconds with the standard RECON-QHY system.
SNR of 4.3 per integration for unocculted signal
Expected flux drop is 30% with SNR of 1.3 for the occulted depth (per occulted point)
Apparent velocity is 2.4 km/sec on the sky relative to the star, or, 2.8 arcsec/hr.
Position angle of asteroid motion is 63.4 degrees
The recommended exposure time corresponds to 4.8 km per image.
The 1-sigma error in the time of the event is 6.7 seconds.
The 1-sigma cross-track error in the shadow position is 30.3 km.
The sky-plane scale is 3106.0 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 19.3 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 7.9 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
