Heavy smoke from peat fires are continuing to blanket Borneo and many surrounding regions across Indonesia, as shown in the image taken by NASA's Aqua satellite.
The red dots indicate hot spots where the satellite's sensors have detected unusually warm surface temperatures caused by existing fires.
Small cumulus clouds are also visible along Borneo's southern coast.
The fires were started by farmers engaged in slash and burn agriculture, a technique that involves burning of virgin rainforest to clear the way for commercial crops such as oil palm and acacia pulp plantations.
The 2015 burning season which began in September, is one of the most severe in the last two decades, with thick gray smoke triggering air quality alerts and health warnings across Indonesia and neighbouring countries.
Many of the fires burn through areas containing soils underlain with peat, a mixture of partly decayed plant material formed in wetlands.
