2022A Call for Gemini GSAOI Proposals


Proposals for GSAOI observations on the Gemini South telescope in Semester
2022A (1 February 2022 - 31 July 2022) are due by


*5:00pm AEDT, Tuesday 5 October 2021.*



In Semester 2022A the Australian astronomical community will have access to
the remaining 2 nights of observing time with the Gemini South Adaptive
Optics Imager (GSAOI). This opportunity is a result of the agreement between
AURA and the ANU team that constructed the NGS2 enhancement to the Gemini
South multi conjugate adaptive optics system. The NGS2 system was
commissioned in October 2019 (see attached the article published in Gemini


The new NGS2 system allows the use of fainter guide stars - the previous
limit with the old system was R=15.5 in good conditions. During
commissioning the loop was closed on a R=18 star in average conditions. This
results in a huge improvement of the sky coverage for GeMS (2.5 magnitude is
approximately equivalent to a gain of 8 times in sky coverage). Acquisition
times have also been reduced by almost tenfold. 


The ANU team was awarded a total of 7 nights of guaranteed time, which they
have kindly offered to the Australian community via this open call for
proposals process. This allocation was split between the 2020B and 2021A
semesters. However, due to the COVID pandemic and challenges associated with
it, the Gemini Observatory allowed some flexibility and will offer the
remaining observing time in 2022A. 


The expectation is to have two or three laser runs of 7 nights each during
the semester, the actual schedule will be based on the demand from the


All new proposals will be reviewed and assessed by ATAC.  The observing time
will be allocated in 'classical' mode, which means that observations will be
scheduled for specific nights. The COVID-19 pandemic restrictions prohibit
international travel from Australia and it is most likely that this
situation will not change in the 2022A Semester. The classical mode
observations will be taken by the Gemini Observatory staff, with remote
assistance (control) from PI teams. The Observatory has a good experience
with such operations and will work with the individual teams to ensure the
best strategy for their observations and the quick access to the raw data.
