Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/15 07:09:18 UTC
J2000 position of star is 05:36:16.3 +16:16:15
Equinox of date position of star is 05:37:49.4 +16:17:09
Star is 144 degrees from the moon. Moon is 30% illuminated.
Stellar brightness G=15.8, apparent brightess of occulting body is G=15.8
Use an exposure time of 0.80 seconds with the standard RECON-QHY system.
SNR of 4.6 per integration for unocculted signal
Expected flux drop is 50% with SNR of 2.3 for the occulted depth (per occulted point)
Apparent velocity is 13.7 km/sec on the sky relative to the star, or, 15.4 arcsec/hr.
Position angle of asteroid motion is 93.3 degrees
The recommended exposure time corresponds to 10.9 km per image.
The 1-sigma error in the time of the event is 0.5 seconds.
The 1-sigma cross-track error in the shadow position is 25.7 km.
The sky-plane scale is 3194.9 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 3.1 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 1.3 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
