Hi Jon,
I'm including this instruction, the object file, and a finding chart
for the class observations.

The project description
-----------------------

Obtain KOSMOS spectra of the galaxy EON_17.154_1.641 for its
stellar population study. The object is a highly inclined, disk
galaxy. The spectrograph's long slit must be oriented along the
major axis of the object (correct rotation angle is specified
in the 3.5m object file).

KOSMOS configuration
--------------------
slit=1.18"
Grism: 3800-6600A Blue, Center

Calibrations
------------
9-12 KOSMOS bias should be taken in the evening or morning time.
5-7 dome flats should be observed in closed dome, with
Br Qz lamps on. The exposure time is 210 sec. Preferable
telescope Altitude is more or less that expected for the
object, e.g. 60 degrees.
At the end of the object exposure petals must be closed,
He + Ne + Ar lamps turned on, and the Arc exposure
to be exposed for 120 sec, at the object's pointing
location.

A spectrophotometric standard star from the list in the
attached object file must be observed for 600 sec. It is
preferable to accompany it with its He-Ne-Ar Acr exposure, see
above. The star must be placed at the center of the slit.

Sky Conditions
--------------
The object is a faint galaxy. The sky can have transparent
clouds, but if the object is not seen in the KOSMOS guider
with reasonable exposure time (~20-30 sec), it makes no sense
to observe it.
It can be observed with the Moon up, although the object-Moon
angle should be greater than 90 degrees.

Object observations
-------------------
The center of the slit should be placed at the center
of the object.
Preferable exposure time is 6 x 1200 sec, minimum - 3 x 1200 sec.

Logging
-------
Please log the frame numbers, exposure time, sky conditions
(photometric or not), and seeing.
I prefer a plain text file with this information rather
than a paper sheet.

Best wishes,
Dmitry
