Driving south on 895 a mile before reaching harbor tunnel in Baltimore a bright light to my left appeared which I thought was residual fourth of July stuff at first. But I quickly realized that its brightness trajectory girth and sparks coming off its sides made me sure it was nothing I've seen before. What struck me was the size of the head of the streak. Oval is my best description of the shape of the yellow descending fireball. A few sparks appeared to come off its sides.
