Safety First, Always!

To ensure that nightly observations at the Gemini telescopes in Hawai’i and Chile run smoothly our day crews perform an extraordinary range of jobs.

Sometimes that work involves potentially dangerous situations. This is why Gemini staff regularly attend mandatory safety training classes to provide the best practices and procedures.

Following the success of similar classes last year, the engineering group recently coordinated another workshop in this series, this time including training for work in confined spaces and for activities performed during maintenance procedures.

Gemini South also extended an invitation for staff to participate from other telescopes in Chile. In addition to Gemini, staff from Cerro Tololo (CTIO), the European Southern Observatory (ESO), and Las Campanas Observatory (LCO) joined in the workshop.

José Manuel Caracena José, a Spanish engineer with extensive experience in observatory safety coordination led the workshop.

Base Facility Operations Status

Gemini South is integrating a new Base Facility Operations (BFO) system to allow nightly operations from the base facilities in La Serena.

The goal of the BFO project is to provide the infrastructure to safely perform telescope operations from the base facilities (Gemini North is already operating routinely in this mode), with new tools for remote assessment, notification and control of telescope systems, instruments and support infrastructure. This includes monitoring and assessment tools for weather, earthquake and network connectivity, as well as improvements and upgrades to the existing systems related to the needs for safe operations from the base facility.

The final project handover for BFO is scheduled for December of this year, with many milestones on the horizon.

In June and July the Facility Protection System (FPS) and the Telescope System Remote Switch (TSRS), and most parts of the environmental sensing system will be ready for testing and the trial operational phase.

In November we will switch control from the summit control room to the base facility in a trial mode. During this time Support Operations Specialists (SOSs) will operate the telescope from La Serena with the help of a BFO team member, and engineering staff who will support operations on the mountain at the beginning of each night.

BFO is a large project that requires the participation of most Gemini departments, including Engineering, Software, Development, Informations Technology Services, the Administration and Facilities group, and even Public Information and Outreach (producing updates like this!)

To summarize, everything is progressing smoothly with the BFO project at Gemini South and we expect to operate completely from the La Serena base facility by the end of this year – watch for updates!

Estatus del Proyecto de Operaciones desde las Oficinas Bases

Gemini's Assistant Engineer Francisco Meza and Electronics Technician Herman Diaz, are working on Cloud cameras & Fog weather sensors control box, which are part of the Environmental monitoring Work-package within the BFO project at Gemini South.

Gemini Sur se encuentra integrando un nuevo sistema de Operaciones desde las Instalaciones Base (BFO, en sus siglas en inglés) para permitir las operaciones nocturnas del observatorio desde La Serena.

El objetivo del proyecto BFO consiste en proporcionar la infraestructura necesaria para realizar operaciones seguras del telescopio desde las oficinas en La Serena (Gemini Norte ya opera de forma rutinaria en este modo), con nuevas herramientas para la evaluación a distancia, la notificación y el control de los sistemas del telescopio, sus instrumentos y las infraestructuras de apoyo . Esto incluye herramientas de seguimiento y evaluación para el clima, terremotos y la conectividad de la red, así como las mejoras y actualizaciones a los sistemas existentes en relación con las necesidades de seguridad de las operaciones desde las instalaciones base.

La entrega del proyecto final para BFO está prevista para diciembre de este año, con muchos hitos en el horizonte.

En junio y julio, el Sistema de Protección de Instalaciones (FPS) y el Sistema de Interruptores Remotos de Telescopio (TSRS), además de la mayoría de las partes del sistema de detección medioambiental, estarán listos para la prueba y la fase operativa de prueba.

En noviembre vamos a cambiar el control del telescopio desde la cumbre a las oficinas de la base de operaciones, en un modo de prueba. Durante este tiempo, Especialistas en Soporte de Operaciones (SOS) controlarán el telescopio desde La Serena con la ayuda de un integrante del equipo de BFO, en tanto que personal de ingeniería apoyará las operaciones en la montaña al comienzo de cada noche.

BFO es un enorme proyecto que requiere la participación de la mayoría de los departamentos de Gemini, incluyendo Ingeniería, Software, Desarrollo, Servicios de Tecnología de Informaciones, el grupo de Administración y Servicios, e incluso Información Pública y Divulgación (¡produciendo artículos como este!).

En resumen, todo avanza sin problemas con el proyecto BFO en Gemini Sur y se espera que a fines de año sea posible opear en forma remota desde las oficinas de la base de operaciones, en La Serena. ¡Síguenos y está atento a las novedades!

Weather Impacts GeMS Run

Weather Impacts GeMS Run

Bad weather and poor seeing significantly impacted the recent run of the Gemini Multi-Conjugate Adaptive Optics Systems (GeMS) and the Gemini South Adaptive Optics Imager (GSAOI). Unfortunately this prevented most of the planned observations from being completed.

Only a small portion of data were obtained for the Large and Long Program (LLP) and Guaranteed Time (GT) programs, and for two queue programs, one from Korea and another from Japan.

During the run (April 13 – 21) we expected to continue the observations for the LLP lead by Dr. Tobias Fritz, complete important observations for the Australian Guarantee time program, and observe high priority targets for queue programs.

GSAOI was removed from the telescope on April 22 and replaced with the Gemini Planet Imager (GPI). GSAOI laser observations will resume again in early June 2016 at Gemini South.

The next GeMS/GSAOI run will be held the first week of June 2016.

Users Play an Active Role in Instrument Upgrade

F2_Installation-6

FLAMINGOS-2 is ready to receive the new band filters. This photo shows a previous removal of the instrument for regular maintenance work.

The Near-Infrared wide field imager and multi-object spectrometer FLAMINGOS-2 (F-2) will be upgraded with two medium-band filters that will split the 1.9-2.5 micron spectral range for sensitive imaging surveys of very red objects.

The improvement is a result of an invitation to the Gemini’s partner community for small instrument upgrade projects. This initiative aims to establish annual proposal calls for science-driven instrument upgrades – including projects that may rely upon in-kind contributions or telescope observing time as compensation.

Gemini’s Science Group issued the first call for proposals in the fourth quarter of 2015 and the award went to Casey Papovich and his team from Texas A&M University. It also includes astronomers from the University of Toronto, Swinburne University of Technology, Leiden University, and Macquaire University.

The new capabilities will cover a wide range of potential science, from detecting young stellar object candidates in deeply obscured star forming regions, to deep K-band imaging to study the demography of high-redshift massive galaxies. Other enabled science includes taking a census of low-mass stars in very dusty environments.

In addition to funding the design, procurement, and testing of the filters, Gemini has awarded the team with 10 hours of telescope time to demonstrate the scientific benefits of the new capability.

The filters are expected to be available and installed in the second half of 2016 and be offered to our user community in semester 2017A.
