Occultation event with (7352) Hypsenor, event index number 1100
Regions able to see the event: SAmericaN
Geocentric closest approach at 2025/06/28 10:20:03 UTC
J2000 position of star is 02:12:43.1 +05:36:36
Equinox of date position of star is 02:14:03.4 +05:43:43
Star is 103 degrees from the moon. Moon is 11% illuminated.
Stellar brightness G=16.4, apparent brightess of occulting body is G=15.8
Use an exposure time of 0.95 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 35% with SNR of 1.1 for the occulted depth (per occulted point)
Apparent velocity is 25.9 km/sec on the sky relative to the star, or, 23.0 arcsec/hr.
The recommended exposure time corresponds to 24.6 km per image.
The 1-sigma error in the time of the event is 1.4 seconds.
The 1-sigma cross-track error in the shadow position is 13.5 km.
The sky-plane scale is 4054.6 km/arcsec.
Diameter estimates:
60.5 km assuming a 5% albedo, aximum of 2.3 sec for a central chord
24.7 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 60.5 km used for deployment plan.
