The week of February 26, 2018

This week we continued with HPF and Laser Frequency Comb (LFC) commissioning. We made a lot forward progress in getting spectra with the comb and had our official “first light”. Below are a few pictures that might help visualize some of what transpired.

A slide that shows the basement of the HET where the HPF and LFC live.

A part of the spectrum from HPF which shows the very regular picket fense of emission lines generated from the LFC just below a stellar spectrum. The spectra are stacked up in an echellogram.

A very happy HPF team, NIST team and HET Night Operations team celebrate first spectrum on the sky. It took a large number of people to get this entire effort going but here are the lucky ones to see it live!
