Now there is a third LIGO plant active in Pisa (Italy) which could give a more accurate information about such correlations and the direction of the gravity origin.
Days ago I wrote:
The LIGO former measurements should be controlled at those pensil shaped gravity incidents.
"The team, led by Andrew Jackson, a physicist at the Niels Bohr Institute in Copenhagen, claims that the troublesome signal could be significant enough to call the entire discovery into question. The potential effects of the unexplained correlations “could range from a minor modification of the extracted wave form to a total rejection of LIGO’s claimed [gravitational wave] discovery,” However,: "LIGO representatives say there may well be some unexplained correlations, but that they should not affect the team’s conclusions."

Not only the sunspots black holes could produce pencil shaped gravity lensing but even dense Planetary micro black holes e.g. in the moon or even star clusters black holes far away , which can be lined up two by two in our direction.
See e.g.:
Are dense star clusters the origin of the gravitational waves discovered by LIGO?
