Observation of three twilight bolides in August, 2013 from Galicia, NW of Spain

Abstract

The Spanish Meteor Network (SPMN) is dedicated to the study of fireballs and bolides which may cause meteorite falls on our planet. These meteorites allow us a better understanding of other bodies from the Solar System and that is why we operate 25 meteor observing stations to monitor the night sky. During the month of August 2013, three bright bolides were observed from the northwest of the Iberian Peninsula, on days 14, 22, and 30. The first one was recorded by the camera from the R. M. Aller Astronomical Observatory (OARMA). There were numerous visual witnesses that could account for them and the atmospheric path of one the bolides was reconstructed from the observation provided by them and the images of the camera. In this work we present the data provided by the witnesses (for all three cases) and a preliminary analysis of one of these events (day 14).
