The glitches have been spotted also in the PMC channels as we can see in the attached figure. 

In the past we have seen that a decrease of the PMC power, related to the temperature increase of the Neovan head can cause an anomalous behaviour of the PSTAB and ITF channels (eLog 62974). As we are facing a similar problem at the moment (Fig. 2), we are going to further investigate this issue as soon as possible.
