Time Check: Please do a clock time check each night before
taking data and verify your time with Loiano observatory at the beginning of the run, and
as often during the run as possible. We have an accurate clock
available for phone clock checks. Please, check the time before each run!!!
Data Transfer: There are two ways to send your data and logs at the
end of each night.
Observing Logs: We ask that you send
a copy of your observation log along with the data, at the same time if
you can.
Run start:
Please start your run on an integral multiple of
ten seconds (times ending in "0").
Check the computer clock just before the start
of a run, synchronizing with your master clock to within 0.1 sec if
possible.
Integration time:
Use 20 seconds integration time for PMT-based systems. Those with CCDs
will have to use their judgement (and/or confer with control center) to obtain the
appropriate balance between signal to noise, cycle time, and duty time.
Filters:
Use B and V filter in all channels.
Comparison and check star for ONE CHANNEL PMT users We have selected standard comparison stars for
V346Ori : At this moment the only comparison star to be used in the campaign is "Comp" of the finding chart.
Positions for check star and sky are shown in the finding chart.
The sequence to be used is :
target-Comp-sky1 * 10 times, then restart sequence
Comparison star for CCD users The comparison star is only "Comp" of the finding chart. No check star needed for the moment
Sky calibration:
Observers with 3-channel photometers should record sky in all three
channels near the beginning and possibly the end of each run to permit
accurate cross calibration. Observers with one channel photometers should take sky
by moving the telescope in the place identified by the findings charts .
Apertures: Please use the
smallest aperture consistent with getting data of good quality (e.g. no
visible loss of light to the edge of the aperture). A general rule of
thumb is to use an aperture approximately 8-10 times the diameter of the seeing
disk. (An aperture too small can lead to light loss out the edges; one too
large adds additional sky noise and possibly opens the field up to
nearby contaminating stars.) Record the size
of the aperture (in arcsec) in your observing log.
!!! Switch to this target only after a communication of the P.I. !!!

If you use the ftp option, upload your data into the pub directory
"pub"
The files must have a prefix fixed for each observatory
in this format: ex. Loiano files loiV_DDMMa.dat Moletai files molV_DDMMa
We will look at the data as fast as they come in, and we'll
contact you promptly if we have any questions about, or problems with, the
data you send.
.
Good luck to each of you.
Please tell us about any
problems so that we can improve the quality of operations in future runs.
