Occultation event with (6002) Eetion, event index number 4067
Regions able to see the event: US
Geocentric closest approach at 2026/08/21 07:28:51 UTC
J2000 position of star is 05:40:54.8 +13:00:34
Equinox of date position of star is 05:42:24.9 +13:01:17
Star is 159 degrees from the moon. Moon is 61% illuminated.
Stellar brightness G=14.9, apparent brightess of occulting body is G=16.2
Use an exposure time of 0.35 seconds with the standard RECON-QHY system.
SNR of 5.4 per integration for unocculted signal
Expected flux drop is 76% with SNR of 4.1 for the occulted depth (per occulted point)
Apparent velocity is 27.1 km/sec on the sky relative to the star, or, 25.0 arcsec/hr.
Position angle of asteroid motion is 102.8 degrees
The recommended exposure time corresponds to 9.5 km per image.
The 1-sigma error in the time of the event is 0.4 seconds.
The 1-sigma cross-track error in the shadow position is 33.2 km.
The sky-plane scale is 3895.5 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 1.7 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.
