UIT Targets Sucessfully Acquired (Whew!):

Days 13--14:

We report here on those proposed UIT targets that, in fact, were successfully acquired. Where possible we provide an optical CCD image of the target or the field.

Note on Filters:

A1 centered at 2500 angstroms with a width of 1200 angstroms
B5 centered at 1615 angstroms with a width of 150 angstroms

Observed at MET: 13/01:53

M63 or NGC 5055 is a pleasant spiral galaxy with multiple arms and a bright inner region. The exposure times were 1149 seconds through B1 and 576 seconds through A1.

Observed at MET: 13/02:53

NGC 752 a galactic stellar cluster was observed for 777 seconds through B5

Observed at MET: 13/03:33

M89 a relatively obscure elliptical galaxy in the Virgo cluster was observed for 992 seconds in B1 and 496 seconds in A1.

Observed at MET: 13/10:27

NGC 1365 is a prominent spiral galaxy in the Fornax Cluster. This exposure was for 1265 seconds through A1 and B5

Observed at MET: 13/11:11

M87 is the brightest galaxy in the Virgo cluster and is among the most massive of all galaxies known. The optical image above shows lots of little fuzz balls which are globular clusters bound to M87. The galaxy has an active nucleus from which an optical and radio jet emanates. M87 usually delights at all wavelengths and these UIT exposures should be no exception. The exposure taken here was for 1485 seconds in the A1 and B1 filters.

Observed at MET: 13/13:32

NGC 1512 is a late type spiral galaxy which is relatively nearby. This exposure was for 948 seconds through B5 and 151 seconds through A1.

Observed at MET: 13/14:17

M92 is thought to be the most metal poor luminous globular cluster in our Galaxy. This exopsure was for a a total of 2446 seconds through A1,A5, B1 and B5.

Observed at MET: 13/20:07

IC2574 is a nearby late type spiral of angular size 13 x 5 arcminutes which is relatively big for most CCD fields. The galaxy fits comfortably into one UIT frame and this exposure was for 1360 seconds through A1 and B1.

Observed at MET: 13/20:54

Baades Window is a famous region of low obscuration at low galactic latitude. This allows us to view into the bulge component of our galaxy for purposes of performing a stellar census there. This exposure was for 1420 seconds through B5 and A1.
