It was not long before two videos showing the passing of the meteor appeared. Being one from the city of Florian\u00f3polis-SC and other one from Imbituba-SC.<\/p>\n<p>The analysis from these two videos, show us that the meteor occurred far away from the coast. This information was confirmed from the images of the\u00a0<a href=\"https:\/\/en.wikipedia.org\/wiki\/GOES-16\">GOES &#8211; 16 satellite<\/a>, which showed a flash about 550 km from Florian\u00f3polis. This flash was occurred at a time compatible with the reports and in the location near of where the triangulation of the two videos pointed.<\/p>\n<p><iframe title=\"B\u00f3lido de Santa Catarina - 24\/03\/2019\" width=\"854\" height=\"480\" src=\"https:\/\/www.youtube.com\/embed\/S0q-5pZqwjQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<p>The video recorded in Imbituba-SC, from the balcony of an apartment, has clear references that allowed to correctly calculate the parameters of the passage of the meteor. However the video recorded in Florian\u00f3polis-SC, on Joaquina beach, does not have so many references. We still managed to extract azimuth and elevation data for the initial and final points of the bolide, evidently with a greater margin of error, but which allowed us to calculate the trajectory and confirm that the glare observed in the GOES &#8211; 16 satellite was really bolide.<\/p>\n<p>After analyzing the satellite images,\u00a0\u00a0<a href=\"http:\/\/www.iag.usp.br\/atmosfericas\/membro\/rachel-ifanger-albrecht\">Dra. Rachel Albrecht<\/a> of Department of Atmospheric Sciences of the IAG\/USP noticed that there were no clouds capable of generating electric discharge in that area and confirmed that the flash could only be generated by the passing of a meteor through atmosphere.<\/p>\n<p>According to the triangulation made by the images from Florian\u00f3polis-SC and Imbituba-SC, together with the information collected by GOES-16 satellite, we come at the trajectory presented below:<\/p>\n<p><a href=\"https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2019\/03\/mapa-1.jpg\"><img data-attachment-id=\"2587\" data-permalink=\"https:\/\/www.bramonmeteor.org\/bramon\/en\/amsterdam-1-de-1\/\" data-orig-file=\"https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2018\/09\/amsterdam-1-de-1.jpg?fit=1024%2C645&amp;ssl=1\" data-orig-size=\"1024,645\" data-comments-opened=\"0\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"amsterdam (1 de 1)\" data-image-description=\"\" data-medium-file=\"https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2018\/09\/amsterdam-1-de-1.jpg?fit=300%2C189&amp;ssl=1\" data-large-file=\"https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2018\/09\/amsterdam-1-de-1.jpg?fit=854%2C538&amp;ssl=1\" loading=\"lazy\" class=\"aligncenter wp-image-2587\" src=\"https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2019\/03\/mapa-1.jpg?resize=517%2C348\" alt=\"\" width=\"517\" height=\"348\" data-recalc-dims=\"1\" \/><\/a><\/p>\n<p>The calculated trajectory indicates a North to South displacement direction. Due to the high margin of error of the Florianopolis data, it is possible that there is a small variation of the initial point to east or west. The calculated initial altitude was 59.3 Km and the final altitude was 32.92 Km. The meteor displaced with an average speed of around 17 Km\/s and at an angle of 18 deg related to the surface.<\/p>\n<p>See below the projection images of the meteor trajectory for each point of view.<\/p>\n<div class=\"tiled-gallery type-rectangular tiled-gallery-unresized\" data-original-width=\"854\" data-carousel-extra='{&quot;blog_id&quot;:1,&quot;permalink&quot;:&quot;https:\\\/\\\/www.bramonmeteor.org\\\/bramon\\\/en\\\/analise-do-bolido-de-santa-catarina\\\/&quot;,&quot;likes_blog_id&quot;:167387043}' itemscope itemtype=\"http:\/\/schema.org\/ImageGallery\" > <div class=\"gallery-row\" style=\"width: 854px;
