Fireball observed July 1st Canada Day evening just before fireworks, crossing sky slightly upwards, south south east then disappearing.Just before the start of Canada Day fireworks, we observed to the east a fireball approximately the size of a searchlight of a helicopter. It was hard to judge the size because we did not know the distance away of the object. It travelled slowly south southeast at an upward angle from the horizon of only around 20 degrees, maybe less.We do not know the visual origin of the light as it only caught our eye when already in the sky. We watched it climb and cross the sky and then it just disappeared. It was orange and circular. This was observed by myself, a 43 yr old man and my 2 children, 13 and 10 yrs old.
