Occultation event with (16070) Charops, event index number 3342
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/03/03 22:50:41 UTC
J2000 position of star is 03:49:29.7 +32:23:03
Equinox of date position of star is 03:51:09.0 +32:27:44
Star is 107 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=16.5, apparent brightess of occulting body is G=15.7
Use an exposure time of 1.00 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 34% with SNR of 1.1 for the occulted depth (per occulted point)
Apparent velocity is 18.9 km/sec on the sky relative to the star, or, 16.5 arcsec/hr.
Position angle of asteroid motion is 102.3 degrees
The recommended exposure time corresponds to 18.9 km per image.
The 1-sigma error in the time of the event is 0.2 seconds.
The 1-sigma cross-track error in the shadow position is 25.4 km.
The sky-plane scale is 4110.5 km/arcsec.
Diameter estimates:
66.4 km assuming a 5% albedo, maximum of 3.5 sec for a central chord
27.1 km assuming a 30% albedo, maximum of 1.4 sec for a central chord
Cross-track diameter of 63.2 km used for deployment plan.
