Occultation event with (7352) Hypsenor, event index number 1467
Regions able to see the event: SAmericaN
Geocentric closest approach at 2025/11/07 05:19:52 UTC
J2000 position of star is 02:09:05.9 +02:27:35
Equinox of date position of star is 02:10:26.2 +02:34:52
Star is 41 degrees from the moon. Moon is 96% illuminated.
Stellar brightness G=15.4, apparent brightess of occulting body is G=14.9
Use an exposure time of 0.70 seconds with the standard RECON-QHY system.
SNR of 5.5 per integration for unocculted signal
Expected flux drop is 38% with SNR of 2.1 for the occulted depth (per occulted point)
Apparent velocity is 16.3 km/sec on the sky relative to the star, or, 18.8 arcsec/hr.
Position angle of asteroid motion is 73.6 degrees
The recommended exposure time corresponds to 11.4 km per image.
The 1-sigma error in the time of the event is 0.8 seconds.
The 1-sigma cross-track error in the shadow position is 19.6 km.
The sky-plane scale is 3116.2 km/arcsec.
Diameter estimates:
60.5 km assuming a 5% albedo, aximum of 3.7 sec for a central chord
24.7 km assuming a 30% albedo, maximum of 1.5 sec for a central chord
Cross-track diameter of 47.7 km used for deployment plan.
