Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/28 02:00:04 UTC
J2000 position of star is 05:30:05.0 +16:22:20
Equinox of date position of star is 05:31:38.2 +16:23:28
Star is 33 degrees from the moon. Moon is 83% illuminated.
Stellar brightness G=14.8, apparent brightess of occulting body is G=15.7
Use an exposure time of 0.65 seconds with the standard RECON-QHY system.
SNR of 9.2 per integration for unocculted signal
Expected flux drop is 69% with SNR of 6.3 for the occulted depth (per occulted point)
Apparent velocity is 16.8 km/sec on the sky relative to the star, or, 19.2 arcsec/hr.
Position angle of asteroid motion is 94.4 degrees
The recommended exposure time corresponds to 10.9 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 3135.2 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 2.6 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
