We present precise data including atmospheric trajectory, dynamics, photometry and heliocentric orbit on the very bright bolide (-18.5 absolute magnitude) over Western Ukraine photographed by 3 Czech and 2 Slovak all-sky cameras of the European Fireball Network (EN) on November 17, 2001. The fireball started its 106 km long luminous trajectory at an altitude of 81.4 km about 10 km SW from Ukrainian town Dolyna and terminated at a height of only 13.5 km. Such low terminal altitude of a fireball is very scarce and this fireball is the deepest ever photographed fireball in history. The meteoroid entered the atmosphere with the velocity of 18.48 km/s and during its flight highly decelerated to the final value of 4.2 km/s. The initial dynamic mass of about 4300 kg was substantially ablated but according to our computations still several hundreds of kilograms of total mass landed on the ground in several fragments near the village Turji-Remety. No meteorite has been recovered yet. The body, before its collision with the Earth, orbited the Sun on an elliptic low inclination orbit with the aphelion in the main belt of the asteroids. Such kind of heliocentric orbit is quite usual for fireballs which penetrate very deep into the Earth's atmosphere and which can produce meteorites.
