The total solar eclipse is due to arrive on Friday morning (March 20), with peak viewing time being around 9.35am. The UK will have a front-row seat - providing there's no cloud cover - to witness this rare phenomenon.
But smog from the continent is also threatening to blank out the skies for many star gazers.
Pollution covering Paris has been blown across the channel and weak winds mean it has settled across the UK.
It will remain for much of Thursday before new weather front will cause it to dissipate by Friday morning. However cloud will still blanket the country, meaning most people will miss the eclipse.
