Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/17 02:05:37 UTC
J2000 position of star is 05:35:29.5 +16:16:55
Equinox of date position of star is 05:37:02.6 +16:17:51
Star is 124 degrees from the moon. Moon is 46% illuminated.
Stellar brightness G=16.5, apparent brightess of occulting body is G=15.8
Use an exposure time of 0.95 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 36% with SNR of 1.1 for the occulted depth (per occulted point)
Apparent velocity is 14.2 km/sec on the sky relative to the star, or, 16.0 arcsec/hr.
Position angle of asteroid motion is 93.5 degrees
The recommended exposure time corresponds to 13.5 km per image.
The 1-sigma error in the time of the event is 0.4 seconds.
The 1-sigma cross-track error in the shadow position is 25.6 km.
The sky-plane scale is 3184.6 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 3.0 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
