Early Saturday morning police and fire crews received calls from concerned residents in Carnegie Street at Claremont, who reported seeing a bright light igniting a fire in a nearby paddock.
Tasmania Fire Service officer Scott Vinen says the blaze was quickly put out, leaving an obvious burnt patch.
He says the bizarre incident has everyone baffled.
"Once we put the fire out, we kind of walked through the fire and tried to find something," he said.
"We thought a flare or something may have landed there, but we couldn't find any cause."
The Fire Service says it will not investigate further.

Flare by local kids ? :D
During the 1970's in NZ I saw a number of locations, which involved both burnt and bleached patches as well as "Rings", some of which were similar to the one shown above.
Many were in the form of a perfectly round patch, or in the form of a "Ring", about 30 feet in diameter.
The width of the bleach markings, were about 9 inches to a 1 foot wide, forming a ring about 30 feet in diameter.
One such area was the Waimata Valley near Gisborn in the latter part of the 1970's, about 1976 1978 if I remember correctly (Long time ago now... LOL.)
Another was left in a paddock at the end of Gloucester St. adjacent to a little town called Patea . in about 1969, or there about.
At the time the town (Patea) experienced a total power black out, lasting the duration of the time the craft was on the ground, according to witnesses who lived at the end of Gloucester St.
