Regions able to see the event: Europe,SAmericaN
Geocentric closest approach at 2026/11/07 02:19:32 UTC
J2000 position of star is 05:59:44.5 +08:57:29
Equinox of date position of star is 06:01:12.7 +08:57:27
Star is 108 degrees from the moon. Moon is 5% illuminated.
Stellar brightness G=16.6, apparent brightess of occulting body is G=15.7
Use an exposure time of 1.25 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 29% with SNR of 0.9 for the occulted depth (per occulted point)
Apparent velocity is 10.9 km/sec on the sky relative to the star, or, 12.5 arcsec/hr.
Position angle of asteroid motion is 49.8 degrees
The recommended exposure time corresponds to 13.6 km per image.
The 1-sigma error in the time of the event is 1.8 seconds.
The 1-sigma cross-track error in the shadow position is 30.1 km.
The sky-plane scale is 3135.0 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 4.2 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.7 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
