Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/23 02:04:42 UTC
J2000 position of star is 04:24:23.3 +52:13:19
Equinox of date position of star is 04:26:28.6 +52:16:55
Star is 41 degrees from the moon. Moon is 96% illuminated.
Stellar brightness G=11.0, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 37.8 per integration for unocculted signal
Expected flux drop is 99% with SNR of 37.5 for the occulted depth (per occulted point)
Apparent velocity is 19.0 km/sec on the sky relative to the star, or, 20.3 arcsec/hr.
Position angle of asteroid motion is 100.0 degrees
The recommended exposure time corresponds to 2.3 km per image.
The 1-sigma error in the time of the event is 0.7 seconds.
The 1-sigma cross-track error in the shadow position is 41.2 km.
The sky-plane scale is 3357.2 km/arcsec.
Diameter estimates:
41.9 km assuming a 5% albedo, maximum of 2.2 sec for a central chord
17.1 km assuming a 30% albedo, maximum of 0.9 sec for a central chord
Cross-track diameter of 38.4 km used for deployment plan.
