Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/05 08:24:24 UTC
J2000 position of star is 05:39:58.4 +16:13:32
Equinox of date position of star is 05:41:31.3 +16:14:17
Star is 91 degrees from the moon. Moon is 16% illuminated.
Stellar brightness G=14.6, apparent brightess of occulting body is G=16.0
Use an exposure time of 0.55 seconds with the standard RECON-QHY system.
SNR of 9.7 per integration for unocculted signal
Expected flux drop is 78% with SNR of 7.5 for the occulted depth (per occulted point)
Apparent velocity is 10.2 km/sec on the sky relative to the star, or, 11.3 arcsec/hr.
Position angle of asteroid motion is 92.5 degrees
The recommended exposure time corresponds to 5.6 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 25.6 km.
The sky-plane scale is 3263.0 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 4.2 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 1.7 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
