Hei, testailen rakentamaani softaa, jolla voi rekonstruoida meteorin radan sen valoisan lennon aikana sekä määrittää radiantin. Tästä tulipallosta on mukavasti havaintoja joiden avulla softaani vosi testailla. Tarvitsisin kuitenkin havaintopaikan tarkat koordinaatit, sekä tulipallon syttymis- ja sammumispisteen koordinaatit (joko azi-alt, tai rec-dec muodossa). Viimemainitut voin toki itsekin kuvasta arvioida, mutta tietysti aina parempi, jos kameransa paremmin tunteva voisi tässä avittaa. Onnistuisikohan? Laittaisin sitten Taivaanvahtiin vielä erillisen raportin analyysistä. Yst Terv Janne Sievinen  (janne.e.sievinen -at- gmail -dot- com)
