Subject: Shift summary 

The intensity of the Seeding decreesed from 850 uJ to 550 uJ during the time between 20:00 and 02:00.

The Spectral purity also got worst, the beam in HIREX looks to have more SASE shoulders.

Between 18 and 20 we show a prossible transiant signal, PPL, of the lower branch. But a problem with the monochromator in the MID opt Hutch trigger the valve to close. After we where not able to see the signal possible effect of laser or X-ray inestabilities.

Problems with the liquidjet, the nozzel got clogged.

Started the aligment of the upper branch of SDL
