A very bright bolide was recorded by four BRAMON cameras at dawn on Thursday, April 23. From the triangulation of the images, it was possible determinete the trajectory of the meteor and its orbit, which is associated with phi Ophiuchids (USG), radiant, one of the meteor showers discovered in 2017 by BRAMON. Check out the video below:
The cameras located in Taquara, Monte Castelo and Florianópolis, detected the bolide at 06:43 UT (03:43 BRT). The meteor with high brightness reached a -6.8 magnitude, exploding over the Region of Hortências in RS.
According to the analyzes carried out by Prof. Dr. Carlos Jung, the meteor began to shine at 106.4 km heigh and extinguished with an explosion at 67.1 km heigh, over the Region of Hortências, above the cities of Nova Petrópolis, Canela and Gramado in Gaucha Sierra.
The triangulation of the images, also allowed calculate of the orbit of this meteor, which caused a pleasant surprise: Although we are in the period of the Lyrids, the recorded meteor doesn’t associated to this rain. The original rain is the phi Ophiuchids that was discovered in 2017 by BRAMON itself and is cataloged in the International Astronomical Union with the acronym USG. Phi Ophiuchids is a rain that has its radiant close to phi Ophiuchi star, in the Ophiuchus Constellation and has its peak on May 11th.
The images were recorded by BRAMON stations at the Heller & Jung Observatory in Taquara, Rio Grande do Sul, managed by Prof. Dr. Carlos Jung, at Monte Castelo in Santa Catarina, managed by Jocimar Justino de Souza and at Florianópolis, also in Santa Catarina, managed by Thiago Paes.
