Regions able to see the event: Australia,NMexico,SMexico
Geocentric closest approach at 2026/11/14 12:35:17 UTC
J2000 position of star is 05:58:04.7 +08:52:08
Equinox of date position of star is 05:59:33.0 +08:52:11
Star is 153 degrees from the moon. Moon is 23% illuminated.
Stellar brightness G=14.0, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.30 seconds with the standard RECON-QHY system.
SNR of 10.0 per integration for unocculted signal
Expected flux drop is 87% with SNR of 8.7 for the occulted depth (per occulted point)
Apparent velocity is 13.0 km/sec on the sky relative to the star, or, 14.0 arcsec/hr.
Position angle of asteroid motion is 65.1 degrees
The recommended exposure time corresponds to 3.9 km per image.
The 1-sigma error in the time of the event is 0.8 seconds.
The 1-sigma cross-track error in the shadow position is 26.3 km.
The sky-plane scale is 3364.3 km/arcsec.
Diameter estimates:
42.7 km assuming a 5% albedo, maximum of 3.3 sec for a central chord
17.4 km assuming a 30% albedo, maximum of 1.3 sec for a central chord
Cross-track diameter of 35.1 km used for deployment plan.
