Using TOS#

TOS (TRAO Observation Status) is a web app accessible through a web browser and profides the following features:

  • Checking real-time TRAO observation status

  • Logging previous observation status

  • Chatting in real-time among observers

  • Messaging for the next observer

The TOS window is always open on the observation computers (both for on-site and remote observation) in the TRAO observation room.

Note

On remote observation computers, due to limited screen space, the TOS window may be in the background, so you may need to use the application switcher to bring the web browser to the foreground.
