This Russian military convoy stretching over 64 kilometres is moving closer to Ukraine's capital.
If it started in Sydney's CBD, it would stretch west past Penrith.
These satellite pictures, taken on Monday by US company Maxar Technologies, show part of the convoy near Ivankiv, north of Kyiv.
In conditions hovering around freezing, hundreds of armoured vehicles, tanks, towed artillery and logistics support vehicles are moving south towards the city.
Here's what we know from the pictures.
Outside Kyiv
These convoys are part of an advance from Belarus in the north, into Ukraine and towards the capital.
A report by the Institute for the Study of War says the next major Russian attack is likely within 24 hours.
Limited logistic support and reinforcements had held back Russia's operations around the capital, but the Institute says that is likely to change and it will play out over the next two to three days.
This bridge on the border of the Kyiv city region was damaged. One image shows smouldering vehicles.
To get to the capital, troops are passing through residential areas.
In Belarus
More troop deployments and ground attack helicopter units were seen in southern Belarus, less than 32km north of the Ukraine border.
Yesterday, UK defence minister Ben Wallace said forces heading from Belarus had been slowed down by Ukrainians defending the crucial Antonov Airport.
But attack lines are also coming from the east.
Where are Russians attacking?
The Institute for the Study of War says Russian forces are increasingly targeting Ukrainian airfields in the west, trying to ground the Ukrainian air force and hurt supply lines.
This is an airfield left smouldering outside Kyiv.
Russian artillery also bombarded residential districts of Ukraine's second-largest city, Kharkiv.
But around Kyiv, the US expects Russian forces to try to encircle the capital in the coming days.
