Occultation event with (16070) Charops, event index number 4358
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/10/07 06:35:14 UTC
J2000 position of star is 06:36:45.7 +32:31:44
Equinox of date position of star is 06:38:30.5 +32:30:16
Star is 55 degrees from the moon. Moon is 13% illuminated.
Stellar brightness G=16.9, apparent brightess of occulting body is G=15.7
Use an exposure time of 2.00 seconds with the standard RECON-QHY system.
SNR of 3.2 per integration for unocculted signal
Expected flux drop is 25% with SNR of 0.8 for the occulted depth (per occulted point)
Apparent velocity is 7.8 km/sec on the sky relative to the star, or, 7.0 arcsec/hr.
Position angle of asteroid motion is 80.9 degrees
The recommended exposure time corresponds to 15.5 km per image.
The 1-sigma error in the time of the event is 0.6 seconds.
The 1-sigma cross-track error in the shadow position is 26.3 km.
The sky-plane scale is 3996.5 km/arcsec.
Diameter estimates:
66.4 km assuming a 5% albedo, maximum of 8.6 sec for a central chord
27.1 km assuming a 30% albedo, maximum of 3.5 sec for a central chord
Cross-track diameter of 63.2 km used for deployment plan.
