Regions able to see the event: Europe
Geocentric closest approach at 2026/12/03 20:19:49 UTC
J2000 position of star is 05:49:55.9 +36:34:32
Equinox of date position of star is 05:51:45.3 +36:34:54
Star is 106 degrees from the moon. Moon is 24% illuminated.
Stellar brightness G=15.7, apparent brightess of occulting body is G=15.3
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 4.1 per integration for unocculted signal
Expected flux drop is 41% with SNR of 1.7 for the occulted depth (per occulted point)
Apparent velocity is 19.5 km/sec on the sky relative to the star, or, 21.8 arcsec/hr.
Position angle of asteroid motion is 112.6 degrees
The recommended exposure time corresponds to 11.7 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 38.1 km.
The sky-plane scale is 3216.8 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, maximum of 2.8 sec for a central chord
21.9 km assuming a 30% albedo, maximum of 1.1 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
