Details:
In recent years, we have had numerous opportunities to observe smoke drifting across from North America, originating from wildfires raging there. This smoke often arranges itself into distinctive bands, somewhat resembling the distribution of sulfur dioxide aerosols released into the atmosphere after volcanic eruptions. However, wildfire smoke typically hovers at lower altitudes.
These bands become visible at dawn, as soon as sunlight reaches them—before that, nothing can be seen; the sky appears just as starry as usual, though the transparency may be slightly reduced. This time, the phenomenon became truly striking about 20 minutes before sunrise. First along the horizon, then gradually higher, sunlight began to illuminate the smoke bands, which turned a pale whitish-yellow almost instantly.
To the untrained eye, the sky at that moment looks as though it's covered in thin cirrus clouds, but a time-lapse video reveals the true nature of the scene.
The bands remain discernible for about an hour after sunrise, after which they blend into a uniform haze. At dusk, the process repeats itself—only in reverse order.
