LIGO events and Celestial Events
There are coincidences among the 16 LIGO detected events and several celestial events.
4 GW events were nearly coincident with a new moon (within 2 days).
2 events nearly coincided with a full moon (within 2 days).
2 events nearly coincided with a perigee (within 1 day).
1 event nearly coincided with a perhelion (within 1 day).
2 events nearly coincided with an alignment between the Moon and Jupiter (within 2 days).
That means 11 out of 16 were within 2 days of a celestial event.
2 other events were within 5 days of a perigee.
All 16 GW events were within 6 days of a lunar or solar celestial event.
Wikipedia has a list of each GW event date and time
The event names have the format: GWyymmdd
where GW150914 event is on 2015-09-14.
Here is the summary. The details will follow, then a conclusion.
Here are those dates and the concident celestial event: full or new moon: FM or NM or PG (Perigee), PH (Perihelion), MJ (Moon - Jupiter alignment).

difference of 0 days is a match, 1-2 is near, 3-6 is questionable, >6 is too far.
On 2019-04-23 was a alignment separation of the Moon and Jupiter of only 1 degree, 38 minutes, at the same RA.
When I did this exercise I expected no frequent correlations between any moon positions and the gravitational wave events.
I am quite surprised by several coincidences.
A new moon puts maximum tidal stress on Earth's crust, with the Sun also aligned. A perigee also does an earth tide regardless of the Sun.
Earth tide is the displacement of the solid earth's surface caused by the gravity of the Moon and Sun. Its main component has meter-level amplitude at periods of about 12 hours and longer.
With the Moon at such a distance I do not know how many days cover most of its significant crust distortion. Maybe it takes only a day or two to relax. I was surprised by its meter-level amplitude.
This observation is probably a random coincidence of dates.
I really can't argue if someone says you can always find some possible pattern between sets of numbers.
In any case, I find this observation interesting. I leave it to reader to their interpretation.
I checked for these coincidences simply because LIGO was designed to detect any disturbance in Earth's crust from a theoretical gravitational wave. The Moon is known to disturb Earth's crust and oceans.
This means all 16 GW events were within 6 days of a lunar or solar celestial event.
I honestly don't know for certain whether this is an appropriate criteria.
If this observation is valid: this is funny if LIGO did not always account for the lingering effects of the nearby moon.
