Occultation event with (6002) Eetion, event index number 4507
Regions able to see the event: Europe
Geocentric closest approach at 2026/10/29 00:13:22 UTC
J2000 position of star is 06:01:32.5 +09:27:37
Equinox of date position of star is 06:03:01.0 +09:27:31
Star is 25 degrees from the moon. Moon is 89% illuminated.
Stellar brightness G=14.5, apparent brightess of occulting body is G=15.8
Use an exposure time of 0.50 seconds with the standard RECON-QHY system.
SNR of 9.6 per integration for unocculted signal
Expected flux drop is 75% with SNR of 7.2 for the occulted depth (per occulted point)
Apparent velocity is 8.8 km/sec on the sky relative to the star, or, 9.9 arcsec/hr.
Position angle of asteroid motion is 30.9 degrees
The recommended exposure time corresponds to 4.4 km per image.
The 1-sigma error in the time of the event is 3.1 seconds.
The 1-sigma cross-track error in the shadow position is 22.1 km.
The sky-plane scale is 3207.0 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 5.2 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 2.1 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
