Bright meteor at the sky of Espirito Santo Brazil

On the night of May 3, three Exoss network cameras recorded a bright meteor over the south of Espirito Santo, Brazil. The fireball entered the atmosphere at a 60 degree entry angle at the place below its initial penetration, above the city Mimoso do Sul  at a height of about 80 km, at a low speed, about 18km / sec, covering about 23 km in about 1.7 secs. Its maximum brightness came close to the magnitude of Venus. Applying the usual criteria of the meteoroid source analysis, together with its orbital elements, such as eccentricity , inclination , semi-major axis,...

Fireball captured on video by Exoss stations on Espirito Santo’s Brazilian state

Exoss station on Espirito Santo state recorded a meteor fragmentation above Minas Gerais state Skies. New Year has only begun and we have good news! A fireball video with many eyewitness. It Occurred in 2017, January 9th at 9:41 (GMT-3). This event was recorded by two Exoss project station in different cities: Colatina and Vitória ( ES – Capital), by the Exoss associates Luciana Fontes and Willian Eugênio. As the bolide images were captured by doubled stations, the parallax calculation was applicable and the trajectory output data had more precise results than bolido.exoss.org report tool. At first, the radiant...

The PRO-AM Lunar Impact project Exoss

In order to attain its goals, exoss project now is launching the lunar impact project – monitoring meteoroids impacts, using  telescope observations of the non-illuminated side of the moon, looking for flashes that could be meteoroids striking the lunar surface, through a remote observatory. The remote observatory : O ROCG – Remote Observatory of Campos dos Goytacazes, was built in this year and is located in the brazilian city, Campos dos Goytacazes, Rio de Janeiro State, by the amateur astronomer  Carlos Henrique Barreto, under the scientific and technical supervision of Exoss coordinator, Marcelo De Cicco. To aim the lunar impact observations goals, a Celestron C-14, f/3.3 and a camera Stellacam Ex attached to the telescope are in use for video monitoring the dark side of the moon. Another camera, Watec 902 H is also available. In the picture, the amateur astronomer Carlos Henrique is setting adjustments for the polar alignment Impact candidates 2005-20016.

Double Camera Configuration Assistant Program for meteor stations

Recently we build a program to assist double cameras coverage configuration. The DOCCA (double camera configuration assistant) software is in its first version, and is based on mathematica language, but yet helps the network to improve double detections meteors. It takes in account the distance stations, the high of an ideal meteor  brightness, and an average ‘r’ factor for a typical  shower. The picture above shows the GUI of DOCCA program, in the example two Exoss stations/cameras of Rio de Janeiro state north region are being evaluated for the best position, SJU1 and CFB1 stations. The temperature map indicates how good...

Fireball over Espirito Santo-Brazil

On 20 October, two cameras of Exoss project – Vix1 and Vix3 station –  registered a fireball crossing over the middle north of Espirito Santo State, in Brazil. It happened at 05:56:18 UTC, just one day before  the Orionids shower peak. As a first approach of  phenomena´s analysis indicates a meteoroid blasting around 100-90 km, and a brightness approximately –8 to –6 mag. Despite of atmosphere nebulosity and passing clouds  during the event, the video is really impressive....
