Images of fireball EN270217_023122 (February 27, 2017, 02:31:22 UT) taken at four different stations. In all cases, north is up, west is to the right, and the fireball was moving generally from the bottom to the top. The scale is the same in all images. At station 5, the fireball moved close to the zenith. The other three cameras imaged the fireball from increasing distances of 100 km, 160 km, and 330 km at stations 2, 9, and 16, respectively (measured on the ground from the middle of the fireball). The fireball entry speed was 31 km s⁻¹ and the maximum absolute magnitude was −12.
