Occultation event with (6002) Eetion, event index number 4095
Regions able to see the event: Australia
Geocentric closest approach at 2026/08/24 21:29:14 UTC
J2000 position of star is 05:43:15.4 +12:52:25
Equinox of date position of star is 05:44:45.4 +12:53:03
Star is 149 degrees from the moon. Moon is 90% illuminated.
Stellar brightness G=16.1, apparent brightess of occulting body is G=16.2
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 3.2 per integration for unocculted signal
Expected flux drop is 53% with SNR of 1.7 for the occulted depth (per occulted point)
Apparent velocity is 25.8 km/sec on the sky relative to the star, or, 24.1 arcsec/hr.
Position angle of asteroid motion is 104.1 degrees
The recommended exposure time corresponds to 15.5 km per image.
The 1-sigma error in the time of the event is 0.5 seconds.
The 1-sigma cross-track error in the shadow position is 34.0 km.
The sky-plane scale is 3861.4 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 1.8 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 0.7 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
