Occultation event with (2674) Pandarus, event index number 1232
Regions able to see the event: SAmericaN
Geocentric closest approach at 2025/08/15 09:51:41 UTC
J2000 position of star is 03:01:49.4 +15:57:24
Equinox of date position of star is 03:03:15.2 +16:03:23
Star is 8 degrees from the moon. Moon is 59% illuminated.
Stellar brightness G=16.5, apparent brightess of occulting body is G=15.0
Use an exposure time of 2.00 seconds with the standard RECON-QHY system.
SNR of 4.2 per integration for unocculted signal
Expected flux drop is 20% with SNR of 0.8 for the occulted depth (per occulted point)
Apparent velocity is 9.2 km/sec on the sky relative to the star, or, 8.5 arcsec/hr.
Position angle of asteroid motion is 79.2 degrees
The recommended exposure time corresponds to 18.4 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 27.1 km.
The sky-plane scale is 3898.2 km/arcsec.
Diameter estimates:
89.9 km assuming a 5% albedo, aximum of 9.8 sec for a central chord
36.7 km assuming a 30% albedo, maximum of 4.0 sec for a central chord
Cross-track diameter of 74.3 km used for deployment plan.
