    keyword=Half wave plate out, slug 15

    It seems that the half wave plate was changed today at 1 pm and flipper
    was not run. There wasn't a halog entry and it wasn't in the shift summary.

    The instructions for changing the half wave plate can be found here.

    These changes have been implemented by hand.
