Abstract
Abstract Meteor showers, seen at regular and frequent intervals, occur when the Earth crosses the orbit of a comet and many small dust particles enter the Earth's atmosphere. In this paper we compare the Southern Delta-Aquariids (SDA) shower recorded by the UVP1 and UVP2 meteor monitoring stations in the Southeastern of Brazil, in 2017 and 2018. These stations are affiliated with EXOSS Citizen Science meteor monitoring network. The SDA meteor shower represented the most active radiant in these two years of data recorded by these stations. 27 detections were achieved in 2017 (between July 12 and August 24) and 15 detections in 2018 (between July 18 and August 20). The meteor properties highlighted and compared throughout the present text are: duration, apparent magnitude and angular velocity. We used estimations provided by the UFOAnalyzer program, since there is no doubled captures from diverse stations far separated. This article helps to highlight the importance of the EXOSS project, aligned with the concept of citizen science, valuing the partnership between amateur astronomers and professional scientists in data collection and wide dissemination of knowledge related to the science of meteors. This work is the result of two scientific initiation projects, with an educational cooperation between the Universidade do Vale do Paraiba (UNIVAP) and the Instituto Federal de Educacao, Ciencia e Tecnologia de Sao Paulo campus Sao Jose dos Campos (IFSP-SJC).
Highlights
Meteoroids are solid spatial particles large enough to produce light caused by the ablation during their passage through the Earth’s atmosphere [1]
This work aims to compare the Southern Delta-Aquariids (SDA) meteors registered by the UVP1 and UVP2 meteor monitoring stations in 2017 and 2018, since this radiant presented the highest numbers of meteors recorded by both stations in these two years
There were no double detections between stations UVP1 and UVP2
Summary
Meteoroids are solid spatial particles large enough to produce light caused by the ablation during their passage through the Earth’s atmosphere [1]. When the Earth crosses the orbit of a comet and many of these particles enter the Earth’s atmosphere, the so-called meteor shower occurs. The radiant of a meteor is the point on the celestial sphere from which the meteor appears. They are best observed in meteor showers, where several meteors seem to come from a single region of the sky (the radiant) [2]. 25% of the meteors are associated to a meteor shower [1]
