NASA has published images of the Holuhraun eruption captured by their satellites from orbit. According to NASA satellite imagery has been scarce until now because of persistent cloud cover over the area and a relatively small number of spacecraft that collect images at high latitudes. However the sky cleared up a little bit in the last few days and the results are quite stunning.
As reported by NASA the image above is a composite of a natural-color observation from August 27 overlaid with an infrared (IR) night view from September 1. The night view combines shortwave IR, near IR, and red wavelengths (bands 9-7-5) to tease out the hottest areas within the vent and lava field. The image shows at least a 1-kilometer fissure and lava flowing in channels.
When the September 1st image was captured the new lava field's size was 3 square kilometres (1.1583 square miles). Now, September 4th, it has spread over 11 square kilometres (4.25 square miles).
