Occultation event with (6002) Eetion, event index number 4730
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/17 08:32:54 UTC
J2000 position of star is 05:56:28.0 +08:26:06
Equinox of date position of star is 05:57:56.0 +08:26:13
Star is 124 degrees from the moon. Moon is 49% illuminated.
Stellar brightness G=14.9, apparent brightess of occulting body is G=15.6
Use an exposure time of 0.75 seconds with the standard RECON-QHY system.
SNR of 9.4 per integration for unocculted signal
Expected flux drop is 65% with SNR of 6.1 for the occulted depth (per occulted point)
Apparent velocity is 13.4 km/sec on the sky relative to the star, or, 15.7 arcsec/hr.
Position angle of asteroid motion is 62.8 degrees
The recommended exposure time corresponds to 10.1 km per image.
The 1-sigma error in the time of the event is 0.9 seconds.
The 1-sigma cross-track error in the shadow position is 33.6 km.
The sky-plane scale is 3068.3 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 3.4 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.4 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
