Regions able to see the event: US,Europe,RECON,UVa
Geocentric closest approach at 2026/11/24 05:34:12 UTC
J2000 position of star is 06:08:15.6 +06:03:09
Equinox of date position of star is 06:09:42.1 +06:02:48
Star is 42 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=16.8, apparent brightess of occulting body is G=15.2
Use an exposure time of 1.65 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 19% with SNR of 0.6 for the occulted depth (per occulted point)
Apparent velocity is 14.0 km/sec on the sky relative to the star, or, 15.6 arcsec/hr.
Position angle of asteroid motion is 85.6 degrees
The recommended exposure time corresponds to 23.1 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 34.4 km.
The sky-plane scale is 3218.6 km/arcsec.
Diameter estimates:
60.0 km assuming a 5% albedo, maximum of 4.3 sec for a central chord
24.5 km assuming a 30% albedo, maximum of 1.8 sec for a central chord
Cross-track diameter of 52.1 km used for deployment plan.

This table contains the target star visibility for registered US sites that are relevant for this occultation. This list has been filtered to only those sites that can see the field and are within range of the shadow given the uncertainties. The observing time range has been calculated to cover the time of the event at each site with allowances for the event timing uncertainty plus time for obtaining a pre and post event baseline lightcurve. This set of stations has a 52.1 % chance of getting at least one chord. There is a 0.0% chance of 2 or more chords assuming clear weather for all.
