Regions able to see the event: Europe
Geocentric closest approach at 2025/03/25 02:31:44 UTC
J2000 position of star is 08:57:37.6 +15:22:41
Equinox of date position of star is 08:59:01.8 +15:16:46
Star is 171 degrees from the moon. Moon is 24% illuminated.
Stellar brightness G=15.5, apparent brightess of occulting body is G=16.4
Use an exposure time of 1.50 seconds with the standard RECON-QHY system.
Expected flux drop is 31% with SNR of 9.5 per integration
Apparent velocity is 6.7 km/sec on the sky relative to the star, or, 6.8 arcsec/hr.
The recommended exposure time corresponds to 10.0 km per image.
The 1-sigma error in the time of the event is 7.5 seconds.
The 1-sigma cross-track error in the shadow position is 39.3 km.
The sky-plane scale is 3543.2 km/arcsec.
Diameter estimates:
41.3 km assuming a 5% albedo, aximum of 6.2 sec for a central chord
16.9 km assuming a 30% albedo, maximum of 2.5 sec for a central chord
Cross-track diameter of 41.3 km used for deployment plan.
