A rocket left a luminescent contrail in its wake as it soared through the atmosphere.

The mysterious cloud came from an Epsilon rocket launched from Kagoshima Prefecture.

This footage was shot by a Nippon TV viewer in Kagoshima at about 6:30 Thursday morning.

The cloud resembles an aurora in the dawn sky.

Japan's space agency says the cloud was formed of water vapor expelled form the rocket about 50 miles up.

The still-hidden sun refracted through the frozen vapor, creating the shining effect.

People all over Kyushu Island saw the cloud. Many came out to take pictures.
