I looked at cosmic ray triggers within one minute around each blip glitch at LHO during ER8 and the first week of O1.  I then put that information into the attached histogram, where each time is relative to the nearest blip glitch.  Each blip could contribute however many triggers were within a minute around the time.

Total time analyzed: 4440 seconds (74 blips, 60 seconds each)

Total Cosmic Triggers: 640 (10.49 per bin in the histogram)

Trigger Rate: 0.144 Hz

Histograms for the triggers around every individual blip glitch can be found here .

I also analyzed 8 hours (from 4 different days) of arbitrarily chosen time from O1 to get a sense of the overall cosmic trigger rate.  I found that the average cosmic trigger rate was exactly the same, .144 Hz .  So the cosmic trigger rate near to blip glitches (within 30 seconds) seems to be exactly the same as the overall average cosmic trigger rate.  This, along with the apparently random distribution of triggers in the histogram, would suggest to me that there is no correlation between blip glitches and cosmic ray triggers.

The original blip times come from this page , however Marissa Walker has gone through the list of times and removed glitches that don't appear to be blips under close inspection.  This significantly reduced the number of times.  The most recent time that I included in my analysis was from Sept 23rd.  I would be happy to run over more recent times if anyone has a more recent list of blip glitches.
