Regions able to see the event: SAmericaN,SAfrica
Geocentric closest approach at 2026/11/15 02:40:26 UTC
J2000 position of star is 05:59:04.1 +29:23:08
Equinox of date position of star is 06:00:47.0 +29:23:08
Star is 153 degrees from the moon. Moon is 28% illuminated.
Stellar brightness G=14.9, apparent brightess of occulting body is G=14.9
Use an exposure time of 0.90 seconds with the standard RECON-QHY system.
SNR of 9.7 per integration for unocculted signal
Expected flux drop is 50% with SNR of 4.8 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 117.3 degrees
The recommended exposure time corresponds to 12.7 km per image.
The 1-sigma error in the time of the event is 0.2 seconds.
The 1-sigma cross-track error in the shadow position is 34.8 km.
The sky-plane scale is 3177.8 km/arcsec.
Diameter estimates:
65.8 km assuming a 5% albedo, maximum of 4.6 sec for a central chord
26.9 km assuming a 30% albedo, maximum of 1.9 sec for a central chord
Cross-track diameter of 59.3 km used for deployment plan.
