Visiting Astronomer's Guide
Rev. Sept. 28, 2022
UPDATE - Starting in Semester 2023A, astronomers will be allowed to observe on site; details will be announced prior to the start of the semester. However, we anticipate that the limit of 2 people per program will be strictly enforced, where this is due in large part to demand for the hotel rather than COVID concerns.
Introduction
This guide describes logistical arrangements for Visiting Astronomers scheduled to observe at the SOAR Telescope. Any questions and booking requests should be addressed to your Visit Coordinator:
| NOIRLab & Chilean Visitors: | Ximena Herreros (ximena.herreros at noirlab.edu) |
| Phone: +56-51-2205215 | |
| All Others: | Marcela Urquieta (marcela.urquieta at noirlab.edu) |
| Phone: +56-51-2205323 |
Please note: Visiting astronomers are normally limited to a maximum of two people, both of whom must be on the original proposal. Additional people or a Co-I not on the original proposal require the approval of the SOAR Director. This policy reflects the standard NOIRLab policy (linked below), and applies to all SOAR partners. The number of observers may be limited by available hotel space.
The SOAR Telescope is located on Cerro Pachón at an altitude of 2,738 m, some 400 m from the Gemini South telescope, and 12 km from Cerro Tololo. The map in this link shows the locations of SOAR, Gemini-South, and the dining and dormitory facilities on Cerro Pachón. Should you need information regarding: Visa requirements to enter Chile, Currency, Customs Procedures, Travelling to La Serena, Taxis and Buses in Santiago and Arrival in La Serena, please see the CTIO Visiting Astronomers Travel Guide.
Before your observing run
- Read through the CTIO Visiting Astronomer's Travel Guide
- Please plan ahead and contact your Scientific Staff support a least 3 weeks before your observing run, so you can discuss your particular instrumentation needs, and requirements for supporting your observations.
- If your time was allocated through NOIRLab or the Chilean TAC, your contacts are the following:
- If your time was allocated through the Brazilian TAC, then your support for any of the SOAR instruments is provided remotely through LNA (e-mail soar.suporte AT lna.br)
- If you are observing through time allocated to the University of Carolina at Chapel Hill (UNC) or to Michigan State University (MSU), the person in charge of SOAR at your department will provide you with the appropriate support.
- Submit your Instrument Setup Form at least 2 weeks before your observing run
- Depending on the instrument and type of observations you will also need to submit special, critical information well in advance:
- If you will be observing with SAM you need to submit your target list at least 2 weeks before your scheduled observations, so that we can submit to the US Laser Clearing House the request for authorized time windows in which each object can be observed with the SOAR Laser Guided Adaptive Optics System
- If you will be observing with the Goodman Multi-Slit Object (MOS) mode, you need to submit your mask configurations at least 1 month ahead of your scheduled observations.
- Contact the CTIO Computer Support staff for setting up your laptop and any other device you plan in connecting to the SOAR and Pachón wireless network (see the CTIO Visitor's Computer Guidelines)
- Visiting astronomers and others should continue to submit their devices’ MAC addresses. Your computer will be enabled to work on all SOAR networks as well as those at the Pachón hotel, on Tololo, and downtown.
- When at the telescope, please connect to the “NOIRLab_Guest” or "PublicWiFi" network unless a direct connection to machines on the primary network is required. That is, the guest network is what should be used for checking e-mail, Skype with collaborators while observing, as well as more personal activities. The password should be available in the control room; if not, just ask. There are enough addresses on the guest network to accommodate any reasonable number of devices; please remember that the AURA conditions of use apply on all AURA networks. Note that from the guest network you cannot (at present) make a VPN connection to computers on the NOIRLab and SOAR internal networks, so if you need to work on your data or copy it to your laptop, you need to be on the restricted network (see below).
- The primary network is now called "SOAR_Restricted". The password is available from your support scientist, day crew staff, or telescope operators.
- If you are engaged in more demanding tasks, it is OK to connect to the primary ("Restricted") network. In particular, visiting astronomers who are transferring data to take home may want to make a direct connection from a laptop. We only ask that you use reasonable judgment in doing so.
- There are both US-style 110V and Chilean-style 220V outlets in the control room; bring an adapter if your laptop has a plug different from either of these.
During your observing run
On your first day, make sure to contact your Support Scientist and the Telescope Operator early on, so you can arrange with them the appropriate time to start your afternoon calibrations, and whether you need twilight observations.
Afternoon calibrations usually start at 4 pm. In special cases, e.g. if very long calibrations are required, an earlier start may be arranged, but this requires special arrangements. Ask your Support Scientist.
Operator schedules - The telescope is run by 2 operators who work overlapping shifts. The first operator comes on duty early enough to perform set-ups and support afternoon calibrations, while the second operator wprks until the approximate end of the night. Chilean labor law and the NSF between them do not provide much flexibility, so the "end of the night" is fixed by contract and specified for a "summer" schedule that runs mid-October to February, and a "winter" schedule that covers the rest of the year. This may limit observers who could otherwise work further into morning twilight.
Remember to fill in your End-of-Night report (Internal Access Only) before going to bed. This is very important, not only because it allows us to keep statistics on telescope use, downtime due to weather or technical issues, but mostly because only if we receive an early report on a technical problem, we can act promptly the next day to try and fix it and have you or the next observer ready for the next science night. Please note that if you have left the mountain and are no longer inside the CTIO network, you will need to connect through the VPN in order to access the Night Reports.
Transportation from La Serena to Pachón and back
SOAR Visiting Astronomers are welcome to use the available carryall services to get to/from Cerro Tololo or Cerro Pachón; however, these must be requested in advance through the Visit Coordinator. The carry-all trip from the La Serena offices to Cerro Pachón is about 1h45m. Please note that the carryall passes to Cerro Tololo to drop off/pick up passengers on the way to/back from Pachon.

Arrival at Cerro Pachón and accommodations Observers arriving Pachón from La Serena will be dropped off by the carry-all minibus at the main dormitory unit (picture on right). If your room was assigned there, head directly to the TV room located in the middle of the main dormitories hallway (go up the staircase upon entering the building). There the key hanger is located. The keys to your room (with your name on it) should be hanging there. If not, go and ask the kitchen staff. If you were assigned a room in the "20-unidades" dormitory extension (second picture on right), then most likely your room keys will be in the main key board at the entrance of the dormitory unit. |

|
Wireless and Ethernet wire connections are available in all dormitories, cables are supplied. Prior to your arrival you should have registered the MAC addresses of any wireless devices you plan on using on the mountain, and should by now have the wifi name and password. Remember to carefully read and follow the CTIO Visitor's Computer Guidelines. There are 110V US-style and 220V Chilean-style electricity sockets, an air humidifying system and heating/cooling. A hair dryer is available in the bathroom and there is a security box in the closet for valuable items. |

Room service
The dormitories and houses are cleaned on a daily basis. Every fourth day a thorough cleaning is carried out and bed and bath linen are changed. Should you need further services, please contact the Mountain Assistant at 440.
Getting from the dormitory to the SOAR Telescope and back
Visitors are prohibited from hiking on the road, due to traffic. If you cannot drive a car, please coordinate transportation with the telescope operators and SOAR day crew. Also, hiking beyond where you are readily visible from the hotel is also prohibited, as NOIRLab does not have the resources to search for you if you go missing. There are exercise machines on the first floor of the hotel; if you want to go running please use the paved road at the summit during daylight only (and pay attention to traffic). Please pay attention to weather conditions as well.
Dining on Cerro Pachón
The dining hall is located in the main dormitory unit, and has a full cafeteria service, with buffet style meals every day. Services are adapted to pandemic conditions. Should you require vegetarian meals or a special diet, please notify your Visit Coordinator in advance so that the kitchen can make the appropriate arrangements.
The new Meal Registration System uses tablets on which you can register for a meal either by entering your visitor ID number or your last name. The tables are located at the near self-service bar; it is important that you register your meal before serving yourself.
Meal Schedule
Night Lunch: At lunchtime, please fill out an order form to get your night lunch at Pachón and hand it to the kitchen staff. Your pack will be ready at dinner time. You must also register the night lunch on the tablet.
Special dietary concerns and precautions
Should you require vegetarian meals or a special diet at Cerro Pachon, please notify your Visit Coordinator in advance so that the itchen can make the appropriate arrangements. While in Chile it is recommended that you eat only peeled or cooked fruits and vegetables. Seafood should only be consumed cooked.
Drinking water
Tap water is currently not fully certified in the AURA-O facilities (La Serena, Tololo and Pachón), so you probably should fill glasses from the dispensers in the dining rooms. Elsewhere in Chile it is recommended that you drink bottled water.
Laundry
There are laundry facilities at the Pachón hotel. Please contact one of the kitchen staff or the janitor for access and for detergent.
