Regions able to see the event: SAmericaN,SAmericaS
Geocentric closest approach at 2026/05/05 04:49:29 UTC
J2000 position of star is 12:32:59.7 -16:52:02
Equinox of date position of star is 12:34:22.3 -17:00:44
Star is 68 degrees from the moon. Moon is 89% illuminated.
Stellar brightness G=16.3, apparent brightess of occulting body is G=16.2
Use an exposure time of 0.75 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 49% with SNR of 1.5 for the occulted depth (per occulted point)
Apparent velocity is 14.8 km/sec on the sky relative to the star, or, 14.9 arcsec/hr.
Position angle of asteroid motion is 129.9 degrees
The recommended exposure time corresponds to 11.1 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 20.3 km.
The sky-plane scale is 3570.7 km/arcsec.
Diameter estimates:
43.8 km assuming a 5% albedo, maximum of 3.0 sec for a central chord
17.9 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 33.3 km used for deployment plan.
