TL;DR: In this article, two airglow CCD imagers, located at Cariri (7.4° S, 36.5° W, geomag. 11° S) and near Brasilia (14.8°S, 47.6°W, geOMag. 10°S) were operated simultaneously and measured the equatorial ionospheric bubbles and their time evolution by monitoring the airglove OI 6300 intensity depletions.
Journal ArticleDOI

Michael J. Taylor,Pierre-Dominique Pautet,Amauri Fragoso de Medeiros,Ricardo Buriti,Joaquim Fechine,David C. Fritts,Sharon L. Vadas,H. Takahashi,F. T. São Sabbas +8 more
TL;DR: In this article, optical and radio measurements were made from Brazil to investigate the occurrence and properties of equatorial Spread F, and to characterize the regional mesospheric grav-ity wave field.
Journal ArticleDOI
First observation of an undular mesospheric bore in a Doppler duct
Joaquim Fechine,Cristiano Max Wrasse,H. Takahashi,Amauri Fragoso de Medeiros,Paulo Batista,Barclay Clemesha,Lourivaldo Mota Lima,D. C. Fritts,Brian Laughman,Michael J. Taylor,Pierre-Dominique Pautet,M. G. Mlynczak,James M. Russell +12 more
TL;DR: In this article, a mesospheric bore was observed over Sao Joao do Cariri (7.4° S, 36.5° W), Brazil by using airglow all-sky imagers, forming a well extended wave front which was followed by short waves from behind.
Journal ArticleDOI
Twin mesospheric bores observed over Brazilian equatorial region
Amauri Fragoso de Medeiros,Igo Paulino,Michael J. Taylor,Joaquim Fechine,H. Takahashi,Ricardo Buriti,Lourivaldo Mota Lima,Cristiano Max Wrasse +7 more
TL;DR: In this article, two consecutive mesospheric bores were observed simultaneously by two all-sky cameras on 19 December 2006 at two different stations: Sao Joao do Cariri (36.5°'W, 7.4°'S) and Monteiro (37.1'S', 7.9'S).
Journal ArticleDOI
Case study of mesospheric front dissipation observed over the northeast of Brazil
Amauri Fragoso de Medeiros,Igo Paulino,Cristiano Max Wrasse,Joaquim Fechine,Hisao Takahashi,José Valentin Bageston,Ana Roberta Paulino,Ana Roberta Paulino,Ricardo Buriti +8 more
TL;DR: In this article, a mesospheric front was observed over Sao Joao do Cariri (7.4 ∘ ǫ S, 36.5 ∘ W) on 3 October 2005 and appeared in the airglow images on the west side of the observatory.
