Occultation event with (6002) Eetion, event index number 1182
Regions able to see the event: SAmericaS
Geocentric closest approach at 2025/08/03 09:06:18 UTC
J2000 position of star is 03:19:00.8 +15:33:52
Equinox of date position of star is 03:20:26.8 +15:39:22
Star is 167 degrees from the moon. Moon is 67% illuminated.
Stellar brightness G=15.0, apparent brightess of occulting body is G=16.0
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 7.7 per integration for unocculted signal
Expected flux drop is 71% with SNR of 5.5 for the occulted depth (per occulted point)
Apparent velocity is 19.0 km/sec on the sky relative to the star, or, 19.3 arcsec/hr.
The recommended exposure time corresponds to 11.4 km per image.
The 1-sigma error in the time of the event is 2.0 seconds.
The 1-sigma cross-track error in the shadow position is 5.5 km.
The sky-plane scale is 3537.9 km/arcsec.
Diameter estimates:
45.7 km assuming a 5% albedo, aximum of 2.4 sec for a central chord
18.7 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 45.7 km used for deployment plan.
