Noticed a drop in range to around 100Mpc (between 97 & 108Mpc). 

  C1PLC4_SHG_STAT shows a conversion efficiency low error. The attached plot shows the error flag state changing at 01:12 UTC on 08/10. There is a downward trend in the SHG_STAT_CONVEFF starting around 23:00 UTC on 08/09. This may be related to the issues documented in aLOG #51177. 

Range has recovered a bit (111.3Mpc). Will monitor and call support if the range continues to suffer.
