It was a good round for visiting instruments.
More than a hundred hours of GRACES pro-
grams were approved; the speckle camera
DSSI and its new variant `Alopeke have been
scheduled for ~115 and ~80 hours in South
and North, respectively; and POLISH-2 will
be returning to Gemini North for an approxi-
mately six night run. describe the data provided. A document
containing the detailed requirements on
delivering processed data products to the
Observatory is now available. We encourage
potential PIs with questions about this re-
quirement to email largeprograms@gemini.

With respect to the division of time between
instruments, the two sites look quite differ-
ent: the South is dominated by GMOS-S,
with FLAMINGOS-2 a distant second (Figure
20). In the North, GMOS-N and GNIRS take
approximately the same amount of time;
the other facility and visiting instruments
will take the remaining time in more or less
equal shares. 2017B Retrospective
APRIL 2018 At Gemini North, the semester started later
than usual while we finished repairing the
shutter in late August. That, combined with
weather loss later in the semester, meant
that we had less science time on-sky than
usual. This adversely hit completion rates in
Band 1, but Band 2 programs held up reason-
ably well compared to previous B semesters.
When we were on the sky, conditions were
reasonably good and so Band 3 completion
rates ended up relatively low.
New LLP Program Policy
Beginning with the 2018 Large and Long
Program proposal cycle, all principal in-
vestigators (PIs) of new Large programs
will be required to submit processed data
to the Gemini Observatory Archive (GOA)
within one year after the program’s origi-
nal planned end date, as stated in the pro-
posal. The data must be in the FITS format,
and contain header metadata such that it
is searchable within the GOA. PIs will also
be required to submit documentation de-
tailing the data reduction procedure and
Now that we’re in 2018A, the time has come
for a brief recap of events in 2017B at the
two Gemini sites. Mixed fortunes with the
weather, plenty of visiting observing, and
some exciting astronomical events charac-
terized the semester.
Hawai‘i
Visiting observers came through Gemini
North fairly regularly, conducting four short
classical runs and three more extended Pri-
ority Visitor runs.
