Microsiem level seemed correlated with IMC isuues this weekend but not further back.

Ibrahim, Camilla

Over the weekend we had a long ~13 hour lock and 2 days with minimal IMC issues, this was during a time when the microseism was low. Plot attached.  We see similar long locks around Novmeber 6th/7th when the microseism was low, but we always have less issues locking when the micorsiem is low, plot attached.

We checked back to the quiet IMC time shown in 80951, between Oct 11th to 16th, but the microseism was actually relatively elevated during this time. Plot attached.

In both plots, between the t-cursors show quieter IMC glitch times.
