What proposal mode should I pick?
- I have a particularly compelling science idea that needs Band 1 treatment asap - Ask for director's discretionary time (DD). Response time is typically less than a week. Proposals can be speculative or not, but typically DD proposals need to be for something really current that warrants immediate high priority.
- I want data soon - Use fast turnaround (FT).
A disc of rocky debris from a disrupted planetesimal surrounds white dwarf plus brown dwarf binary star. The white dwarf is the burned-out core of a star that was probably similar to the Sun, the brown dwarf is only ~60 times heavier than Jupiter, and the two stars go around each other in only a bit over two hours.

Gemini South staff Javier Fuentes and Joy Chavez conduct remote observations from the control room in La Serena, Chile.
On February 17th Gemini reached another significant milestone with the celebration of the official handover to Base Facility Operations (BFO) at Gemini South. It took more than 2 years to complete this important step and involved all departments from Gemini South.
The Gemini North laser system has suffered a significant set back with a hardware and optics fault. Recovery of the system is unlikely and priority will go to commissioning the South Toptica laser, followed by the North Toptica laser. The February 2017 North LGS run is cancelled, and LGS will not be offered for semester 2017B regular programs at Gemini North. The queue coordinators are identifying LGS programs that can get useful science using a natural guide star or very good (IQ20) seeing conditions.
In response to recent changes in requirements, the Association of Universities for Research in Astronomy, Inc (AURA) announces that the original RFP has been revised. Only Bidders who previously submitted proposals are eligible to submit revised bid proposals.
Revised Bid Opens: March 23rd, 2017
Revised Bids are due: March 31st, 2017 3:00 pm HST
Please see the revised bid requirements for details pertaining to Revised RFP.
Figure 1: Minimum ionizing luminosity of extended AGN-ionized clouds along the projected radius. These Hubble Space Telescope data show a luminosity drop in the last 20,000 years before our direct view of the nucleus, characteristic for all AGN of this study.
Gemini-North is in need of poor weather programs that can take CC80 or worse and/or IQ Any using NIRI or GNIRS ONLY. If you have an idea for a program that can take such conditions, please see the Poor Weather Proposal Process web page for more information on applying for Band 4 time.
The following five tables provide various exposure time limits. Constraints are due to a number of factors, more than one of which may need to be considered for a given NIRI configuration:
