Occultation event with (15033) 98VY29, event index number 3798
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/06/17 03:17:57 UTC
J2000 position of star is 12:28:38.8 -14:46:34
Equinox of date position of star is 12:30:01.4 -14:55:19
Star is 79 degrees from the moon. Moon is 6% illuminated.
Stellar brightness G=12.2, apparent brightess of occulting body is G=16.7
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 19.2 per integration for unocculted signal
Expected flux drop is 98% with SNR of 18.9 for the occulted depth (per occulted point)
Apparent velocity is 6.8 km/sec on the sky relative to the star, or, 6.2 arcsec/hr.
Position angle of asteroid motion is 48.2 degrees
The recommended exposure time corresponds to 0.8 km per image.
The 1-sigma error in the time of the event is 2.3 seconds.
The 1-sigma cross-track error in the shadow position is 36.4 km.
The sky-plane scale is 3972.3 km/arcsec.
Diameter estimates:
43.8 km assuming a 5% albedo, maximum of 6.4 sec for a central chord
17.9 km assuming a 30% albedo, maximum of 2.6 sec for a central chord
Cross-track diameter of 33.3 km used for deployment plan.
