To learn extra of The Economist’s information journalism go to our Graphic Detail web page.

AFTER MONTHS of hypothesis, Ukrainian forces seem to have begun their long-awaited counter-offensive. On June 4th Russian army sources reported that Ukrainian forces had launched assaults on 5 axes in Russian-occupied Donetsk province, within the east of the nation. Ukrainian sources have been preserving conspicuously quiet. As information from the bottom slowly filters out, The Economist has constructed a mannequin that makes use of satellite tv for pc information to provide a glimpse of the battle from the skies.

Our system depends on satellites that circle over Ukraine twice a day and use thermal imaging to detect high-temperature occasions in locations unobscured by clouds. We use a machine-learning system to estimate whether or not these occasions are associated to the battle, by evaluating patterns with what was noticed earlier than Russia’s full-scale invasion in 2022. It’s removed from excellent, but it surely presents a constant and impartial information to possible army exercise within the nation.

Analyzing the info from June 4th and fifth, the mannequin recognized war-related fires at a number of factors alongside the frontline. Most of those fires have been concentrated across the cities of Zaporizhia (Ukrainian-held) and Donetsk (Russian-held), the place there have been stories of serious escalation within the night time between June 4th and fifth. Russian forces declare to have repelled many of the assaults.

Though our mannequin can be utilized to trace the counter-offensive, war-related fires could also be the results of Russian assaults in addition to Ukrainian ones. The mannequin detected fires within the Ukrainian metropolis of Dnipro, the place airstrikes on June third, considered brought on by Russian missiles, killed a baby and injured 22 folks. In latest days the variety of war-related fires has been greater in Ukrainian-held or contested territory than in firmly Russian-controlled areas.

The general variety of war-related fires has not elevated prior to now few days. This may be due to the constraints of the info: evaluating the uncooked variety of fires by means of time will be tough because the satellite tv for pc captures solely a snapshot in time because it flies over. Many analysts imagine that Ukraine is at present solely probing Russian forces, searching for vulnerabilities—or creating them—earlier than committing its strongest items and artillery firepower. If the Ukrainians really have begun their counter-offensive, and the climate stays clear, our mannequin could detect much more exercise within the days to come back.
