Analisys of a June Lyrid fireball

Abstract

The June Lyrids (JLY) were first observed by Dvorak in 1966 [1]. Its activity period was determined to extend from June 11 to June 21, peaking on June 16 with a zenithal hourly rate of about 9. However, evidence for its existence has been virtually zero since the 1970s. So, additional observations of this shower are necessary to improve our knowledge about the poorly known June Lyrid stream. In this sense, the development of a continuous observing campaign from different observing stations can be very helpful to record multi-station events, as these may provide precise orbital and radiant information. Here we present the preliminary analysis of a bright multistation JLY bolide imaged in the framework of the SPanish Meteor Network (SPMN) in 2012 (Figure 1). As a result of our spectroscopic campaign, we have also obtained the emission spectrum produced by this event. This has provided an insight into the chemical nature of JLY meteoroids.
