I was looking over the PSL this morning and I noticed that in addition to the changes mentioned in Rick's aLOG from last week there was a sharp increase in the diffracted power in the ISS. From 10% to 41% diffracted power. Could this have something to do with the decrease in the transmitted (and sum) light for the PMC? The power decrease in the transmitted light from the PMC and the increase in diffracted light are both around 30%.
