Note: Time of the fireball is given for the beginning of the light curve record taken by the brightness sensor of the autonomous fireball observatory at Kunzak Observatory (EN st.2). Ondrejov record was taken by long focus (360mm) horizontal camera. The average standard deviation for any measured point on the fireball trajectory is only 12 m.
