Occultation event with (6002) Eetion, event index number 4565
Regions able to see the event: Australia
Geocentric closest approach at 2026/11/04 18:02:11 UTC
J2000 position of star is 06:00:18.5 +09:05:07
Equinox of date position of star is 06:01:46.8 +09:05:04
Star is 79 degrees from the moon. Moon is 20% illuminated.
Stellar brightness G=16.4, apparent brightess of occulting body is G=15.7
Use an exposure time of 1.00 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 33% with SNR of 1.0 for the occulted depth (per occulted point)
Apparent velocity is 10.3 km/sec on the sky relative to the star, or, 11.7 arcsec/hr.
Position angle of asteroid motion is 45.8 degrees
The recommended exposure time corresponds to 10.3 km per image.
The 1-sigma error in the time of the event is 2.1 seconds.
The 1-sigma cross-track error in the shadow position is 28.6 km.
The sky-plane scale is 3152.5 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 4.5 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.8 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
