Occultation event with (6002) Eetion, event index number 4609
Regions able to see the event: Australia
Geocentric closest approach at 2026/11/08 16:28:31 UTC
J2000 position of star is 05:59:19.0 +08:52:25
Equinox of date position of star is 06:00:47.1 +08:52:25
Star is 126 degrees from the moon. Moon is 1% illuminated.
Stellar brightness G=16.2, apparent brightess of occulting body is G=15.6
Use an exposure time of 0.85 seconds with the standard RECON-QHY system.
SNR of 3.4 per integration for unocculted signal
Expected flux drop is 37% with SNR of 1.3 for the occulted depth (per occulted point)
Apparent velocity is 11.3 km/sec on the sky relative to the star, or, 13.0 arcsec/hr.
Position angle of asteroid motion is 52.3 degrees
The recommended exposure time corresponds to 9.6 km per image.
The 1-sigma error in the time of the event is 1.6 seconds.
The 1-sigma cross-track error in the shadow position is 30.4 km.
The sky-plane scale is 3123.6 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 4.1 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.7 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
