Regions able to see the event: Europe
Geocentric closest approach at 2026/03/14 19:56:28 UTC
J2000 position of star is 03:20:27.7 +08:40:00
Equinox of date position of star is 03:21:52.4 +08:45:35
Star is 107 degrees from the moon. Moon is 19% illuminated.
Stellar brightness G=12.9, apparent brightess of occulting body is G=16.6
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 11.8 per integration for unocculted signal
Expected flux drop is 97% with SNR of 11.4 for the occulted depth (per occulted point)
Apparent velocity is 29.4 km/sec on the sky relative to the star, or, 25.5 arcsec/hr.
Position angle of asteroid motion is 62.7 degrees
The recommended exposure time corresponds to 3.5 km per image.
The 1-sigma error in the time of the event is 0.7 seconds.
The 1-sigma cross-track error in the shadow position is 15.1 km.
The sky-plane scale is 4156.4 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 1.5 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 0.6 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
