A fireball at night, as bright as a cresent moon - 27.3.2018 at 00.07 Helsinki, Pukinmäki Observation number 72035

Visibility IV / V

Esko Lyytinen, Ursa (Etelä-Suomi)

I didn't see it, I got a fireball camera. It’s probably the brightest thing I’ve gotten on my camera in a few years. It was clear, but partly because it was pretty close. There are known images from six different stations. The entry speed was 25 km / s and went off at 29 km. It was so fast that there wasn’t much material left down. Probably disintegrated, and I don’t know how many larger head fragments there would be in number (not very much at least), but the largest ones are barely 10 grams larger if at all. So there is no need to look. According to estimates, what came down until it fell a few kilometers west of Hämeenlinna.

The duration of the camera observation was 3.64 seconds.

Helsingin havainnon kans samaan aikaan näin Kuopiossa tähdenlennon, joka oli mielestäni tavallista isompi ja lähempänä. Tulosuunta myös luode.

Voiei, kun en ole ollut ulkona juuri tällöin. Hyvä että siitä saatiin kuva kuitenkin! :) Hämeenlinassa näkyy usein tähdenlentoja. Itsekkin näin tämän vuoden alussa isoimman mitä olinkaan nähnyt niin tässä Tammi- Helmikuussa.  Onkohan paikalla jo käyty minne meeori tippui? Pitää itsekkin hommata teleskooppi, sekä jonkinlainen yö kamera :)

Ei ole käyty paikalla. VAlitettavan vähän siitä jäi jäljelle. On kyllä edelleen tutkittavana uusien kameramittausten avustamana ja harkittavana kannattaako käydä.
