24th June … 18:35:26 UTC – 18:37:21 UTC = Full Moon

25th June … 04:22:59 UTC – 07:20:35 UTC = Lunar standstill South 25’38’S

30th June … 07:01 UTC – 07:27 UTC = Moon located on ATB threshold

A test sample to demonstrate how this data relates to seismicity !

On 19th May between times 20:40 UTC – 21:06 UTC, the moon was located on the sunset threshold during “First Quarter” moon phase.

Load tab with “Fourmilab” and input 2021-05-19 20:40:00 UTC … select “From Moon” and click “Update”. The data will display moon coordinates as 33’56’W – 16’23’N.

Load tab with “Sunrise / Sunset Map” … click on “Normal” and select “Hybrid” (personal preference) … place the cursor on coordinates 33’56’W – 16’23’N Central Mid-Atlantic Region. Change date to “Wednesday 19 May 2021, and zoom in the map as required, and locate cursor within stated coordinates until sunset reads as 20:40 UTC… a few arc minutes can make a big difference !

Load tab with “Time & Date” … select “Site Map” and scrol down to “Sun and Moon Calculators” … select “Day and Night world Map”. In the data boxes input 19/5/2021 20:40:00 and click on “Change time”. This will display a visual representation of the moon located on the sunset threshold.

To confirm that 20:40 UTC represents the first minute that the moon was located on the sunset threshold. Select “Fourmilab” and deduct one minute so the time reads as 20:39 UTC. The data will display moon coordinates as 33’41’W – 16’24’N. Select “Sunrise / Sunset Map” and reposition the cursor accordingly. The data will show that sunset occurred at these new coordinates at 20:40 UTC, therefore, it does not correspond with the moons position at 20:39 UTC.

Select “Fourmilab” and input 21:06 UTC … the data will display moon coordinates as 40’13’w – 16’18’N. Select “Sunrise / Sunset Map” and position the cursor accordingly. The data will show that sunset occurred on these coordinates at 21:06 UTC. To confirm that this time represents the “last minute” that the moon was located on the sunset threshold. Advance the time in “Fourmilab” by one minute, and follow the previous procedure.

According to the represented online tools used in this analysis, the moon was located on the sunset threshold during its “First Quarter” moon phase for a total of 27 minutes.

Load tab with “Jekophoto” … select “latitude” 34.58 – “longitude” 98.36 … select “Month / Year” May 2021 … select “Mode:” and choose “Sunrise / Sunset + Twilight (Civil, Nautical & Astronomical)” from the drop down list … click on “Override” (for UTC times) … click on “Submit”. The displayed list will indicate that Astronomical Twilight began at 20:40 UTC on 19th May on these coordinates. The latitude / longitude figures were taken from the EMSC published earthquake list, and represent the location of the M 7.3 Southern Qinghai, China epicentre, which occurred on 21st May at 18:04:14 UTC !

If you select “”Start New Search” at the bottom of the list, and input “latitude” 25.74 – “longitude” 100.05. The list will show that Astronomical twilight began at 21:05 UTC on these coordinates… one minute prior to the moon exiting the sunset threshold. The coordinates were published in the EMSC earthquake list, and represent the location of the M 6.1 Yunnan, China epicentre, which occurred on 21st May at 13:48:37 UTC… 4 hours 16 minutes prior to the M 7.3 Southern Qinghai event !

In past years, have sourced four websites for the procurement of twilight data: UNSO (United states Naval Observatory)… data from this site has been unavailable since October 2019 due to upgrades, but also delayed due to the pandemic. In-The-Sky website, which developed a fault in April 2021… and has currently not been rectified. Heavens Above website and Jekophoto, which are both operational, but on many occasions the data is out of alignment by one minute. Therefore, the calculations I have provided here, are only as accurate as the available data sourced online.

A first preliminary test of this example, would “undoubtedly” favour a coincidental conclusion. Many years of experience employing ephemeral time points to this methodology, would “inevitably” conclude that there is nothing coincidental about these correlations. It is logical to assume coincidence, but “seasoned” forecasters would also take into account the “Chance Factor” i.e. The frequency of “Significant” seismic events in China, compared to the Philippines or Indonesia etc. However, this “First Quarter” example is not testament to a reliable method in the search for pre seismic anomalies. But it may be a “contributing” factor towards causality. Testing previous “First Quarter” moon periods would unlikely produce similar correlations. And this is because the moon is never at the same position, or distance relative to earth during “any” of the listed data periods !

Check out the times listed here, as visualised in one of the “Time & Date” maps. And see if you can determine when a solar / lunar element is going to be located on one of the “Usual Suspects” !
