Science Operations Announcements

Observing databases offline

June 10th, 2008

Starting on Tuesday, June 10 the Gemini Observatory observing databases will be upgraded in preparation for semester 2008B and so will not be accessible by the Observing Tool (OT) or the web report forms. The Gemini North update will be on Tuesday, June 10 and the Gemini South update will be on Thursday, June 12. After the updates ToO triggers will only be possible via the URL mechanism until the new OT is released. The 2008B OT will be available on Friday, June 13 and this will be needed for subsequent fetch/store operations. Please check this site for further announcements.

Gemini North currently accepting poor weather proposals

May 2nd, 2008

Gemini North welcomes poor weather proposals . Note that reliable guiding with the peripheral wave-front sensor (P2) at the optimum frequency requires a star brighter than R~13.5 in clear, dark skies, so in cloudy conditions we can observe only programs with R<11.5 guide-stars. For the GMOS OIWFS the same limit applies. For GMOS-N, only imaging or R400 and B600 spectroscopic programs will be considered.
