Abstract

This work presents a statistical study on the captures of meteors from the Southern Delta-Aquariids (SDA) shower. The records were performed by the cameras of the meteor monitoring stations UVP1 and UVP2 of the EXOSS network. The stations are installed in São José dos Campos, SP, at the Astronomy and Space Physics Observatory of the University of Vale do Paraíba (UNIVAP), in cooperation with the Federal Institute of Education, Science and Technology of São Paulo (IFSP). The SDA shower occurs annually from July to August. Meteor records from the years 2017, 2018, 2019 and 2020 were analyzed. In 2017, 27 records were obtained between July 12th and August 24th, with peak activity on July 27-28th; in 2018, 12 records between July 18th and August 20th, peaking on the night of July 29-30th; in 2019, 45 meteors were recorded between July 11th and August 13th, peaking on July 27-28th; and in 2020, there were 22 records between July 25th and August 7th, peaking on July 28th, with about a third of the SDA meteors recorded that year. In the four consecutive years, the SDA meteors had an average duration of 0.18 s, 0.23 s, 0.23 s, and 0.21 s; average apparent magnitude of -1.1, -1.2, -0.8 and -1.1 and average linear velocity of 47.1 km/s, 51.4 km/s, 49.0 km/s, and 45.7 km/s, respectively
