Happy new year to you too!
Thanks for the feedback, I was hoping that with the recent appearance of two interstellar objects recently that it was time for some interstellar meteors |

The combination of brightness and angular velocity of this meteor is unique to me, does anyone have anything similar? The AV was analysed to be 36.03 degrees/sec and mag -4.2, class Sporadic. Robert ... |

Hi SonotaCo,
Just to give you an update on the latest findings on the 'object' (maybe you have seen this already). It appears the object must have been briefly captured in orbit around the Earth ... |

Thanks for your help on this, I don't normally do any of these calculations myself as I leave it for the experts in Armagh! I have emailed them again to see what sort of range of heights the object c ... |

O I think the problem might lie with the fact I used the time-stamp on the video frame, rather than counting the number for frames between the two points? Since counting frames would give a more accur ... |

Hi SonotaCo, Thanks for your screenshots showing this operation of UFOA I think the differences in our calculations comes from the fact I used the main object at the lead of the train and when I ... |

Hi SonotaCo,
I have attached the files needed for analyzing the fireball. I am not sure how best to use the UFOAnalyzer in this case because there are so many objects. I think it will have to b ... |

Hi SonotaCo,
I have been making some 'back of fag packet' calculations based on written reports and my own video and I did arrive at a speed of around 10km/s for the object as you say. The height ... |

Hi SonotaCo,
Unfortunately the other station in Armagh says they did not capture the 'meteor' because it was 'too low'. Our stations are only about 50 miles apart so we have our (6mm) cameras poi ... |

Hi SonotaCo, Yes space debris is a suspect but because the fireball travelled east to west, it is unusual. I am sure we will know more later today. I have found a report on this web page here (Armag ... |

Hi All, Tonight I captured the 'biggest' meteor I have so far recorded in the almost 8 years operation of my meteor camera I have sent an email to the other meteor recording station in Armagh to ... |

Lol, we seem to grow the same rose in our garden! It is a good variety. Yours look much healthier than mine, but I suppose that's because you are growing it in its native environment since its a yel ... |

Ah good, will have to test this myself! I wonder what on earth was wrong? I was beginning to think Vista was going to be remembered in the same way as Windows Millennium Edition!! |

Hi SonotaCo,
I have received an email from an Italian amateur astronomer called Ferruccio, who is wondering if it would be possible to make the Reports from UA2 as 'rich' as UA1. I think he means ... |
