Larger BNS range drops

Figure 1 There have be a dozen of larger BNS range drops during last night. Usually the 25min glitches cause drops of up to 5Mpc. There has been many drops of 10-20Mpc in BNS range. A question is if the 25 min glitches have become louder, or if we have a new family of loud glitches that has started yesterday.

Quick entry, with attached figures, just to note that the 25-minute glitches have not become more intense, and no other glitch families appear strong enough to explain the large range drops observed between October 1 and 2. The overall glitch rate is relatively low, compared to the period after the Spring Break.

It also appears that only a small fraction of the range drops larger than 5 Mpc occur in close proximity to any glitch. A dedicated correlation analysis may shed more light on the actual cause of these drops.
