Regions able to see the event: SAmericaN,SAmericaS
Geocentric closest approach at 2026/11/19 05:27:14 UTC
J2000 position of star is 03:12:50.7 +03:24:06
Equinox of date position of star is 03:14:15.0 +03:30:04
Star is 61 degrees from the moon. Moon is 67% illuminated.
Stellar brightness G=15.9, apparent brightess of occulting body is G=15.3
Use an exposure time of 0.65 seconds with the standard RECON-QHY system.
SNR of 3.7 per integration for unocculted signal
Expected flux drop is 38% with SNR of 1.4 for the occulted depth (per occulted point)
Apparent velocity is 18.4 km/sec on the sky relative to the star, or, 19.7 arcsec/hr.
Position angle of asteroid motion is 65.8 degrees
The recommended exposure time corresponds to 12.0 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 24.3 km.
The sky-plane scale is 3367.7 km/arcsec.
Diameter estimates:
56.0 km assuming a 5% albedo, maximum of 3.0 sec for a central chord
22.9 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 50.8 km used for deployment plan.
