misunderstood apparition, becomes a spacecraft or similar 20th Century-related technology entity. They were frequently connected with swampy or marshy conditions on the one hand and described as having a yellow core, violet edge and sometimes red. More recently some have been attributed as being methane-based （ $ \mathrm{C H_{4}} $ ）with a trigger of $ \mathrm{P_{2} H_{2}} $ (hydrogen phosphide).

17. As a sample of the pedigree of what is reported today, much further back (AD 584) brilliant rays of light which seemed to collide were reported and (in AD 585) 'rays' or 'domes' were observed in France. On 3 August, AD 989, three brilliant round objects were seen to join together. A fire breathing dragon came out of the sea. In Japan a 'spinning ball of fire like a red wheel hovered' with many witnesses. While from the terrace of Windsor Castle on 18 August 1783 four eminent scientists (including Fellows of the Royal Society) observed and reported (Philosophical Trans. Royal Soc. 1784) an object which hovered, moved, changed luminosity and changed shape, brightened and finally, exploded. [This, in fact was probably ball lightning rather than an earthlight]. Other historical earthlight areas (which will be relevant when a database analysis is done for the present day) are:

- Llambedt, Barmouth and Harlech (see Ley Line/Fault Line map) and Llangolan. (40 mile wide strip).

- Haverfordwest, St. Brides Bay, Milford Haven, 'Stack Rocks'.

- Colwyn Bay to Shotton (24km wide extension inland).

- Denbigh (e.g. 1979 and 1984).

18. During the Second World War what were (now understood) clearly earthlights were reported by Commander-in-Chief Devonport. In 1915 Naval Intelligence investigated phenomena (feared to be of German origin) both in the Warminster and Dartmoor areas and further displays are recorded in 1981 at the Standing Stones of Drizzlecombe. Similar phenomena are reported in the USA. These are often reported for several days, weeks, or months in a particular area - after which they are not seen again, perhaps for years.

19. It appears that there may be more than one type earthlight since medieval miners were well aware that their interest in the phenomena was the proximity of earthlights to copper and iron ore.

## GEOLOGICAL

20. As an aid to the statistical analysis of locations of UAP reports, Figure 8 shows the geological structure of the UK. This may be required if it becomes necessary to:

- Isolate what are believed to be earthlights to specific geographic and geological locations and types of rock formation.

- Further correlate (and thus eliminate those UAPs) with rock types known to produce earthlights when under seismic stress, (as it is suggested that low magnitude seismic disturbance may be sufficient to provide the conditions for light phenomena).

21. Fault Systems There are several Earth Fault-Systems which cross the United Kingdom. The location of these is shown for the whole country (known as the DENT Fault System) at Figure 9.
