Science Operations Announcements
The Gemini South Observing Database will be offline 2017-May-25 from approximately 9:30 AM - 2:00 PM CST while work is done on the network infrastructure.
Update May 27th
Telescope is now back in operation after the snow and ice being removed from the dome.
Update May 26th
The poor weather has continued and impeded science operations. The conditions are now improving and a special team will travel to the summit on Satirday the 27th to clean the dome from ice and snow, and if all goes well we will be able to open on Saturday the 27th.
Update May 19th
The Gemini South observing database is not accessible as of 9:00am on April 27, 2017 due to a network hardware failure at CTIO. Repair work is ongoing but there is currently no estimate of when this will be repaired. This will prevent program sync and auxiliary file transfers. This announcement will be updated as we learn more.
Update April 28: The network link has been restored but communication with the observing database may be unreliable.
Due to a recent change in the JPL Horizons service the ephemeris lookups for non-sidereal targets in the OT and PIT are currently not working. We are currently investigating the issue and we have identified a solution. If the change to Horizons is permanent then we will release new versions of the OT and PIT within the next few days. For now Gemini staff will manually update the ephemerides for non-sidereal targets in the queue.
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.
