Min Min lights

Australia
Channel Country, western Queensland; the road between Boulia and Winton

Min Min lights — a nocturnal luminous object, discoid, with blurred and shifting edges, of apparent diameter between a quarter and half the full Moon; white, or else green, yellow, red or blue; suspended a little above the horizon.

On an Australian country track a three-horse wagon has stopped: ahead, above the dark plain, three discoid lights float motionless at the height of the horizon, beneath the moon.

Variants and names: Min Min light, Min Min lights: a colonial name, from the place name Min Min, a tiny settlement with a staging post on the road between Boulia and Winton. The etymology of the place name is uncertain and must be declared as such: a derivation from an Aboriginal language of the Cloncurry area has been suggested, or else from the name of the hotel, and neither is demonstrated. The languages of the country are Pitta Pitta and, further north, Kalkatungu
What is told: A nocturnal luminous object, discoid, with blurred and shifting edges, of apparent diameter between a quarter and half the full Moon; white, or else green, yellow, red or blue; suspended a little above the horizon. It seems to follow the traveller, or to go before him, or to withdraw as one approaches, and it vanishes abruptly. The corpus is made up overwhelmingly of accounts by drovers, drivers and travellers of the Channel Country.
What it was forthe author’s reading: In the colonial corpus the narrative function is clear: a marker of the danger of nocturnal space for those travelling alone, and a binding agent of outback identity. From the mid twentieth century an economic and explicit one is added, tourism. On the Aboriginal side I formulate no functional hypotheses: the accessible documentation does not allow it.
Where it is attested: The earliest account cited is of 1838, but it is not located in the Boulia area and may concern a different phenomenon. The official local version places the first sighting in the area in the 1890s, by a grave behind the Min Min Hotel — this is local tradition, not a period text. The canonical case of the corpus is the drover's episode of 1918; there follow a much-cited account by Henry Lamond in 1937 and the first systematic collection, Maureen Kozicka, The Mystery of the Min Min Light, 1994. The decisive study is John D. Pettigrew, «The Min Min light and the Fata Morgana. An optical account of a mysterious Australian phenomenon», Clinical and Experimental Optometry 86(2), March 2003.
Caution: It is the only entry in this atlas that has an experiment behind it, and that is the reason it is worth reading to the end. Two recurrent formulas need correcting. The first is «inverted mirage»: the phenomenon is a superior mirage, and the inversion is the thermal one, not that of the mirage — the Fata Morgana is already the superior case. The second is «Pettigrew proposed a theory»: that is reductive, because he reproduced the lights. To be rejected, on the other hand, is the objection that the lights predate colonisation and therefore cannot be headlights: it is a non sequitur, because the mechanism works with any light source, campfires included. Secondary sources report, attributing it to Aboriginal people, the observation that sightings are said to have increased with the European entry into the outback and that the older accounts described stationary lights while recent ones describe them moving: this is a claim that circulates almost only at second hand and I report it as such — if, however, the lights are refractions of real sources, the shift from campfires to vehicle headlights would make that distinction physically coherent.

Reality checkestablished

What has been established today.

The explanation is the Fata Morgana, a superior mirage. After a hot day there forms at night, in contact with the ground of the Channel Country, a layer of cold dense air with a thermal inversion, which behaves as an optical waveguide: it bends the rays along the curvature of the earth and carries the image of a light source beyond the geometrical horizon, for tens or hundreds of kilometres. The observer has no reference by which to judge the distance, and every movement he makes alters the optical path — hence the apparent pursuit and the abrupt disappearances. But the point is not the mechanism: it is that in 2003 Pettigrew put it to the test. Leaving six observers at the camp, he drove some ten kilometres, crossing a rise that put him out of the line of sight, and pointed his headlights towards them. The observers reported by radio that they could see an oscillating light just above the horizon, about half the size of the full Moon, turning from red to orange, to yellow, to green: a canonical Min Min. Then he switched off the headlights and the light disappeared; he switched them on again and it came back. This turns a correlation into a causal link. A few accounts at very short range fall outside the mechanism — though these could be errors in judging distance, which is exactly what a mirage induces. The alternative explanations in circulation do not hold: no luminescent barn owl has ever been caught, and marsh gas is implausible in an arid environment.
