Fireball, Meteorite…?

Several thousand meteors of fireball magnitude occur in the Earth’s atmosphere each day. The vast majority of these, however, occur over the oceans and uninhabited regions, and a good many are masked by daylight. Those that occur at night also stand little chance of being detected due to the relatively low numbers of persons out to notice them.

Additionally, the brighter the fireball, the more rare is the event. As a general thumb rule, there are only about 1/3 as many fireballs present for each successively brighter magnitude class, following an exponential decrease. Experienced observers can expect to see only about 1 fireball of magnitude -6 or better for every 200 hours of meteor observing, while a fireball of magnitude -4 can be expected about once every 20 hours or so.

    At the time of the fireball sighting in Durham, CA on June 10, there was a loud boom and shaking of the ground. I thought it was a sonic boom. People thought a meteor hit the ground and there was a discussion on social media with hundreds reporting the noice and the fireball sighting.

      I saw it and I live in North Auburn. It did not go across the sky like you see shooting stars rather it came down then disintegrated kind of like a firework… Was very bright.

    It literally went over my head and burned out about 10 feet away & about 20′ in the sky!!!.??????? And *Left a “smoke like” line behind it & dissapeared – or just ended…?
    ( like a airplane line of smoke in the sky))
    Paradise Ca about 845pm- 8-55pdt
    It was like a firework or a falling star going through the air. It was very
    bright, maybe even a bit of color… no noise! What did I see??

      What color? Faint green, almost like a copper fire? Last week the institute of near earth objects set out an advisory of possible meteor slyly the chance of a strike was 1 in 125. It is possible that they maybe more

    I witnessed a fireball on the 7th at 230 am and then again on the 10th at 3am the first one went slowly across the sky and then went down the second one slowly went straight down

      The slow moving fireball, could you see the flames undulating, like a marshmallow on fire?

        I had this exact experience by shaver lake California. On either the 25th or 26th the orb was slow moving, about the size of the moon half of it was on fire so it looked like a crescent red crescent moon. I noticed it was slowly dropping and when I looked close I realize that what ever it was it was on fire

    I was taking pictures of Venus on 4/1/20 and have photos (250 mm zoom) of an asteroid; glowing green on one side. I took several shots in sequence which show the object as it/we travel away from each other. They can be found on my Coincidence NOT page (Facebook)

    About a month ago we witnessed 2 flaming objects, the second one about two minutes later, following what seemed to be the same trajectory, from West to East at about 10:30pm across the Miami, Florida sky.

    So these fireballs have nothing to do with the astroid that nearly hit us on the 7 of June?? Came within the moons orbit then three days ltr we get two fireballs ..kinda odd

    I was out driving late night on June 11th, 2020 to early morning June 12th, 2020. I was out in the country and saw two balls flying past the Summer Triangle asterism in the Willamette Valley, Oregon. There was also bright flashes of red lightning farther south, but no sound. It was a very interesting night to be out and about.

    I saw two last night (Sept 24th 2020) at 7:42pm at PCH Malibu coming from up above Pacific. One came first towards earth and made a curve and went up higher until I couldn’t see it anymore like those party balloons that fly far away, then the second one come along and does the same thing.

    The fireball I saw was in the Morning. Orange flaming ball. I was driving down 101 fro San Jose to Redwood City, CA from a night shift as a Security Officer. I should have pulled over and videoed it. It was spectacular.
