The incredible photograph, taken in Bali on Thursday, shows Mount Agung below a lenticular cloud which looks like a hat.
Lenticular clouds typically form when moist air passes over a mountain or volcano, creating a beautiful crown of water vapour.
The clouds have no bearing on whether a volcano will erupt, although the photo also captures a plume of steam rising above Mount Agung’s peak.
Bali volcano evacuees have been living under a level four volcano alert since September 22 when seismic activity began surging underneath Mount Agung.
Volcanic movement appeared to have settled at the start of this week, but the Bali volcano has since been rocked by two earthquakes.
On Tuesday a magnitude 6.7 quake struck in the Flores Sea, just northeast of Bali, but was not enough to trigger an eruption.
This was followed by a magnitude 5.2 earthquake, which hit the Banda Sea in Indonesia’s Maluku Islands yesterday (October 25).
More than 180,000 people in Bali have been forced to abandon their homes to escape a possible Mount Agung eruption.
The vast majority of this number are staying in evacuation camps on the island.
Pak Ade Andreawan, of the IDEP Foundation, revealed that most of the evacuees are desperate to return home to their normal lives.
“They have their garden, their crops, their temple,” he told ABC News.
“Some of them are stubborn. They say, I don’t want to go out from my house, this is the only one that I have, I will try to guard my house.”

Mount Agung has not erupted for nearly 55 years. In 1963 explosions killed more than 1,100 people.
The consensus among volcanologists is that an eruption could still happen at any time.
Dr Janine Krippner, who has been monitoring Mount Agung closely for more than a month, said an eruption is “more likely than not”.
But she stressed that volcanic eruptions are notoriously difficult to predict. “There are too many unknowns, even with the best technology,” she said.
