How to Report your Problem and Filling the Service Requests

When reporting problems, be sure to include the following critical troubleshooting information:



1. Time problem occurred

2. Telescope position on the Selsyn dials, and on the VDU during problem

3. At time of failure was telescope tracking, or slewing?

4. Anything that could help the staff try to repeat and diagnose the problem during the day.

Any technical problems encountered during the night, that you can not resolve fully with the assistance by phone of the 4m or WIYN telescope operators; should be reported in a "Service Request". It is a request for maintenance service from the staff, and it will ensure you have action taken to remedy your problem.




• http://www.noao.edu/noaolocal/andes/ service/ ( opens in new window )
  
  This will ensure that the problem is responded to as quickly as possible, a full compliment of the technical, engineering and scientific staff receive these "Service Requests" in the form of email, as soon as you submit it. Be sure to provide to the telescope position, and any other relevant operational settings that where present when the problem occurred. More information is always better than having the staff have to try and guess at what went wrong under what circumstances.
  
  To read responses to your Service Requests , just go to the service home page, and the most recent requests will be showing at the top of the list. To check to see if you request was sent in correctly, just go to the service web site and look at this same list. To add additional comments or to provide further information to help the staff repeat your conditions, just click on the ADD link when viewing the request you wish to add to.

This keeps visitors out of the observing and control room areas. Be sure this door gets closed, or strangers will be wandering in to your control room with your things in it.




Report info to 4meter Operator at x8620

Each morning, the 4m Operator ( x 8620 ) has to fill out a time use log, including your names, the instrument used, seeing measurements, time spent open, and a report of any problems or issues. They will normally call you at the end of the night. Please call them if you are getting ready to leave and have not given them the needed information yet.
