We have time-exchange programs with Gemini and Keck. The instruments written in italics are those of Gemini or Keck.

* This proposal has been accepted in the category of Intensive Program and will be assigned 5 nights for the following 5 semesters.

NOTE
In order to compensate surplus telescope times, which resulted from cancellations due to UPS failure and instrument damage caused by hurricane, five backup proposals (see *1 below) were newly accepted and supplemental nights were added to originaly accepted four proposals (see *2 below).
