Phase 2: Programming Observations

This page is for astronomers with Phase 1 proposals that have been accepted, and who therefore have been awarded observing time on the LT. Users will be informed by email when their proposal is ready to be populated with observations.

Phase 2 User Interface

Successful applicants with time allocated on the LT must submit their observations using the Phase 2 User Interface (phase2UI), an online Java tool. Note that observations will NOT be prepared by LT staff, though users are welcome to contact phase 2 support should they have questions or comments.

To start the phase2UI press the button below. To help new users becomes accustomed with the system, a "Getting Started" tutorial is provided. A Comprehensive Guide is also available. Returning users may simply wish to refer to the instrument-specific pages provided below. As ever, if you have any queries not covered in the tutorial or instructions, please contact LT Phase 2 Support.
