Regions able to see the event: SAmericaN,Senegal
Geocentric closest approach at 2026/09/20 04:55:26 UTC
J2000 position of star is 06:02:43.9 +31:27:25
Equinox of date position of star is 06:04:27.9 +31:27:17
Star is 168 degrees from the moon. Moon is 63% illuminated.
Stellar brightness G=14.4, apparent brightess of occulting body is G=16.0
Use an exposure time of 0.40 seconds with the standard RECON-QHY system.
SNR of 9.5 per integration for unocculted signal
Expected flux drop is 82% with SNR of 7.8 for the occulted depth (per occulted point)
Apparent velocity is 16.0 km/sec on the sky relative to the star, or, 15.0 arcsec/hr.
Position angle of asteroid motion is 50.9 degrees
The recommended exposure time corresponds to 6.4 km per image.
The 1-sigma error in the time of the event is 2.2 seconds.
The 1-sigma cross-track error in the shadow position is 14.7 km.
The sky-plane scale is 3838.4 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, maximum of 3.4 sec for a central chord
21.9 km assuming a 30% albedo, maximum of 1.4 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
