Regions able to see the event: Europe
Geocentric closest approach at 2026/11/11 21:38:27 UTC
J2000 position of star is 05:37:39.6 +16:15:06
Equinox of date position of star is 05:39:12.7 +16:15:57
Star is 167 degrees from the moon. Moon is 7% illuminated.
Stellar brightness G=14.6, apparent brightess of occulting body is G=15.9
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 76% with SNR of 7.4 for the occulted depth (per occulted point)
Apparent velocity is 12.6 km/sec on the sky relative to the star, or, 14.1 arcsec/hr.
Position angle of asteroid motion is 93.0 degrees
The recommended exposure time corresponds to 6.9 km per image.
The 1-sigma error in the time of the event is 0.5 seconds.
The 1-sigma cross-track error in the shadow position is 26.2 km.
The sky-plane scale is 3216.2 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 3.4 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 1.4 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
