Regions able to see the event: Europe,SAmericaN,Senegal
Geocentric closest approach at 2026/10/27 01:55:11 UTC
J2000 position of star is 06:15:39.6 +06:36:12
Equinox of date position of star is 06:17:06.2 +06:35:33
Star is 52 degrees from the moon. Moon is 99% illuminated.
Stellar brightness G=16.2, apparent brightess of occulting body is G=15.4
Use an exposure time of 2.00 seconds with the standard RECON-QHY system.
SNR of 5.9 per integration for unocculted signal
Expected flux drop is 34% with SNR of 2.0 for the occulted depth (per occulted point)
Apparent velocity is 5.1 km/sec on the sky relative to the star, or, 5.4 arcsec/hr.
Position angle of asteroid motion is 37.7 degrees
The recommended exposure time corresponds to 10.3 km per image.
The 1-sigma error in the time of the event is 6.2 seconds.
The 1-sigma cross-track error in the shadow position is 14.4 km.
The sky-plane scale is 3416.5 km/arcsec.
Diameter estimates:
60.0 km assuming a 5% albedo, maximum of 11.7 sec for a central chord
24.5 km assuming a 30% albedo, maximum of 4.8 sec for a central chord
Cross-track diameter of 52.1 km used for deployment plan.
