Occultation event with (6002) Eetion, event index number 4517
Regions able to see the event: Australia
Geocentric closest approach at 2026/10/29 16:42:54 UTC
J2000 position of star is 06:01:26.6 +09:25:18
Equinox of date position of star is 06:02:55.0 +09:25:13
Star is 19 degrees from the moon. Moon is 83% illuminated.
Stellar brightness G=15.6, apparent brightess of occulting body is G=15.8
Use an exposure time of 1.10 seconds with the standard RECON-QHY system.
SNR of 6.9 per integration for unocculted signal
Expected flux drop is 54% with SNR of 3.7 for the occulted depth (per occulted point)
Apparent velocity is 8.9 km/sec on the sky relative to the star, or, 10.1 arcsec/hr.
Position angle of asteroid motion is 32.7 degrees
The recommended exposure time corresponds to 9.8 km per image.
The 1-sigma error in the time of the event is 3.0 seconds.
The 1-sigma cross-track error in the shadow position is 22.5 km.
The sky-plane scale is 3201.2 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.
