To understand trends that show up on charts reflecting the date and time of Full Moons and the Equinox, bear in mind that you are analyzing Navy data and not just the actual progress of the moon and earth. Look at this from the standpoint of the Navy, and what they were tasked with. Indeed, it has taken a slight amount of time more for the slowing earth to arrive lined up for the Equinox. This is a sync point taken at midnight and thus not easily fudged, so reflects the actual slowdown, unannounced, to date. This is the trend line for Equinox, taking more time to arrive, and is the more obvious as it has only one factor to consider, the Earth's orbit around the Sun. The Equinox is computed, by the Navy, and only actually measured every 4 years (in accordance with leap year syncing). This is because during the 4 years that it takes to complete a leap year cycle, the Equinox per definition is around the globe, probably 1/4 turn each turn or so each year for a given Spring or Fall Equinox. Why don't they do an actual measure as it goes around the globe? Because most of the equator, or a good part of it, is over ocean. To measure the exact split second that the sun tips over the equator would require more stability than a ship can provide. Wave bobble, and the ship to be certain it is at the exact coordinates must use guidance systems that could be off a hair, etc. So they rely on a computated Equinox for 3 out of 4 years. But then they do measure the Equinox from a set physical land position, every four years, and this is what is late to arrive (at that physical point!).
The Full Moon operates differently, as this has two factors to consider, the moon's orbit around the Earth as well as the turning of the Earth, and thus is more varied
and less easy for the general public to follow. We have mentioned that to pre-set the data to make the Earth's slowing less obvious, the Navy shortened the Full
Moon periods in their data charts, and this began shortly after the confirmed existence of Planet X in 1983. This pre-setting was done so that the slowing Earth
took fewer days between Full Moons, in their charts, so that the eventual actual slowdown of the Earth would hopefully match their charts during a time of greater
curiosity and scrutiny. But prior to this decision to pre-set the data in anticipation of a significantly slowing Earth, the Navy dealt with a gradually slowing Earth.
A Full Moon, to be visible from Earth, must line up the Sun, Earth, and Moon so that the Moon has full sun and is visible as such from the Earth. This puts the
Moon to the back half of the Earth, for such a view. During the slowing rotation of the Earth, the Sun and Moon truck along as usual, not slowing. Thus, the Moon
is positioned to present itself as full on time, but the spot on Earth predicted to be able to view a Full Moon may not be in position, if the Earth is rotating more
slowly. The Earth thus seems to take longer, in a very gradual slowdown, for a given spot on Earth to arrive where it can view the Full Moon. The added time is
only allowing the Earth to position itself for a view. But at a certain point in this slowing process, those looking to view the full moon will not be in position on the
proper night. At first, the moon is viewed on this horizon, then overhead, then on the other horizon, but still able to be viewed on the proper date. The Full Moon is
almost always sought or noticed at night, when it is dramatic. During the day, the degree of fullness can be confused by sunlight disbursing through the atmosphere.
Thus it was in anticipation of a literal day difference between viewing Full Moons, with the Full Moon seeming to arrive that much early, that the chart data was
Until the actual discovery of Planet X in 1983, there was great reluctance, due to the possibility of discovery, to change the predicated date/time charts. The astronomical community is exacting, and should the tampered data be discovered, the evidence could not be retracted or lost. But panic reigned, during the days when the cover-up over Planet X was being hatched, and steps were taken that give evidence of this panic.
