UIT Targets Sucessfully Acquired (Whew!):

Days 10--11:

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: 10/00:33

M94 or NGc 4736 is an early type spiral galaxy with tightly would spiral structure and a dominant, luminous central bulge. There is a prominent ring of star formation that is somewhat visible but overexposed in this CCD image. This exposure was for 1724 seconds through A1 and B1.

M51 is an extremely well-studied galaxy which is interacting with a small companion NGC 5195. This tidal interaction is exciting spiral structure in M51 and gas flows resulting in areas of intense star formation. This exposure was for 1840 seconds through A1 and B1.

Observed at MET: 10/12:59

The Coma Cluster of galaxies was observed for 1850 seconds through the A1 filter. This will be an interesting object to see if any galaxies were actually detected in the UV has the center of coma is a very dense region and home to old, dead galaxies.
