COS Highlights
 NUV / FUV HV Turn-on complete
 NUV/FUV Functional Tests complete
–
–
Darks: NUV ~70 counts/sec (10x less than STIS/NUV);
FUV ~1 count/resel/3-hours
OSM drift: few measures to date, but definitely present;
TAGFLASH can remove
 COS-to-FGS Alignment established
 COS NUV (imaging) “first light” on 11 June
–
–
F2V astrometric target in NGC-188
Counts ~30% higher than predicted
