After the WFU there will be a number of new instruments:

HRS = High Resolution Spectrograph
LRS2 = Low Resolution Spectrograph
VIRUS = Visible Integral-Field Replicable Unit Spectrographs
HPF = Habitable Zone Planet Finder

Each of these instruments has its own blog.

On August 12 we will start the Wide Field Upgrade for the HET. The first task will be to remove the outer ring of mirrors plus a few extras until we reach our storage capacity of 46 mirrors.

The 2013-3 period

The 2013-3 period started Aug 1 and will officially end when the Wide Field Upgrade begins, Aug 12. After August 12th we will be removing 46 mirrors over 5-8 days. During that time we will attempt science with an ever decreasing pupil size an with growing scattered light.
