Telescope status

    (cf. see the reflectivity degradation of current primary mirror in UM report.)

  • Suprime-Cam is not available from S17B.
  • Hyper Suprime-Cam (HSC) is available under a "shared-risk" mode in S18A.
  • VAMPIRES can be operated simultaneously with CHARIS/SCExAO NIR observations.

User support

  • A new observing planning tool, hskymon, is opened. It is useful for checking target visibility, finding standard star, checking finding chart, searching AO guide stars, etc. (2017/7/11)
