The fires on Borneo had been burning for several weeks now. During the regional dry season (roughly August-October), fires are common, despite Indonesias efforts to crack down on illegal burning.
AQUA 25 October 2006
This image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Aqua satellite from 25 October 2006, shows the haze in the area. The image is a photo-like image, made from MODIS observations of visible light. Smoke appears grayish white in contrast to the bright white of clouds. Fires detected by MODIS are marked in red.

II. Fire Weather and Fire Danger Monitoring and Early Warning
Regional Fire Weather
The Regional South East Asia Fire Danger Rating System (SEA FDRS) is a joint effort between the Canadian Forest Service (CFS) and the Malaysian Meteorological Service (MMS), supported by the Canadian International Development Agency (CIDA). Daily updated SEA Fire Danger Rating can be downloaded on the following website of MMS, and background information on the project can be found at the SEA FDRS Project website.
Latest example of a SEA FDRS product: The Fire Weather Index (FWI) values shown on the map are numerical ratings of fire intensity. Information from the Initial Spread Index (ISI) and Build Up Index (BUI) is combined to provide a numerical rating of fire intensity. This index is used to indicate the difficulty of fire control based on the head fire intensity and fire fighting capability.
Information on the Indonesian Fire Danger Rating System (Indonesian FDRS) is provided by the Indonesian Bureau of Meteorology and Geophysics (BMG) in Jakarta. The site provides information for fire managers working to prevent and control vegetation fires and smoke in Indonesia.

Fire Weather Index (FWI) forecast for this week (left) and the predicted FWI total for next month (right) for the Western Pacific (1-3) and the Pacific Ocean (4-6) regions. The weekly total forecast and the monthly forecasted total refer to 00:00 hrs UTC, which is local noon at dateline (180° longitude). Forecast time is 12:00 hrs noon UTC (Greenwich) corresponding to local evening time in mainland and insular SE Asia. (Source: ECPC Fire Weather Index Forecast)
