Regions able to see the event: SAfrica
Geocentric closest approach at 2026/11/24 23:09:24 UTC
J2000 position of star is 05:55:53.1 -07:46:52
Equinox of date position of star is 05:57:10.9 -07:46:44
Star is 41 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=13.9, apparent brightess of occulting body is G=14.4
Use an exposure time of 0.25 seconds with the standard RECON-QHY system.
SNR of 8.9 per integration for unocculted signal
Expected flux drop is 60% with SNR of 5.4 for the occulted depth (per occulted point)
Apparent velocity is 18.4 km/sec on the sky relative to the star, or, 19.6 arcsec/hr.
Position angle of asteroid motion is 55.2 degrees
The recommended exposure time corresponds to 4.6 km per image.
The 1-sigma error in the time of the event is 0.6 seconds.
The 1-sigma cross-track error in the shadow position is 33.8 km.
The sky-plane scale is 3364.8 km/arcsec.
Diameter estimates:
93.8 km assuming a 5% albedo, maximum of 5.1 sec for a central chord
38.3 km assuming a 30% albedo, maximum of 2.1 sec for a central chord
Cross-track diameter of 96.0 km used for deployment plan.
