Occultation event with (6002) Eetion, event index number 4265
Regions able to see the event: Europe
Geocentric closest approach at 2026/09/19 02:58:09 UTC
J2000 position of star is 05:56:19.9 +11:42:42
Equinox of date position of star is 05:57:49.4 +11:42:49
Star is 164 degrees from the moon. Moon is 53% illuminated.
Stellar brightness G=15.5, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 5.0 per integration for unocculted signal
Expected flux drop is 63% with SNR of 3.1 for the occulted depth (per occulted point)
Apparent velocity is 16.2 km/sec on the sky relative to the star, or, 16.1 arcsec/hr.
Position angle of asteroid motion is 118.9 degrees
The recommended exposure time corresponds to 9.7 km per image.
The 1-sigma error in the time of the event is 1.3 seconds.
The 1-sigma cross-track error in the shadow position is 27.9 km.
The sky-plane scale is 3603.7 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 2.9 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
