“…there are at least 2 other than beginning points (k, j ≤ n) along the trajectory such as V k < V j < V e . In principle, recent proliferation of instruments and methods dedicated to observing meteors makes it possible to fulfill this condition even for such small meteor particles as the Draconids (Borovička et al 2007;Kero et al 2012;Ye et al 2013;Vaubaillon et al 2015). In ordinary cases, when equally reliable data are provided along the observed trajectory (e.g.…”

Despite ablation and drag processes associated with atmospheric entry of meteoroids were a subject of intensive study over the last century, little attention was devoted to interpret the observed fireball terminal height. This is a key parameter because it not only depends on the initial mass, but also on the bulk physical properties of the meteoroids and hence on their ability to ablate in the atmosphere. In this work we have developed a new approach that is tested using the fireball terminal heights observed by the Meteorite Observation and Recovery Project operated in Canada between 1970 − 1985 (hereafter referred as MORP). We then compare them to the calculation made. Our results clearly show that the new methodology is able to forecast the degree of deepening of meteoroids in the Earth's atmosphere. Then, this approach has important applications in predicting the impact hazard from cm-to metersized bodies that are represented, in part, in the MORP bolide list.

“…The outburst was successfully observed by a number of teams using various techniques (e.g. Kero et al 2012;Vaubaillon et al 2013). Here we report the results of our simultaneous spectral, photometric, and dynamic observations of eight relatively bright Draconid meteors.…”

We analyzed spectra, trajectories, orbits, light curves, and decelerations of eight Draconid meteors observed from Northern Italy on October 8, 2011. Meteor morphologies of two of the meteors are also presented, one of them obtained with a high resolution camera. Meteor radiants agree with theoretical predictions, with a hint that some meteors may belong to the pre-1900 meteoroid trails. The spectra confirm that Draconids have normal chondritic composition of main elements (Mg, Fe, Na). There are, nevertheless, differences in the temporal evolution of Na line emission. The differences are correlated with the shapes of the light curves and the deceleration rates. Our data confirm that Draconids are porous conglomerates of grains, nevertheless, significant differences in the atmospheric fragmentation of cm-sized Draconids were found. Various textures with various resistance to fragmentation exist among Draconid meteoroids and even within single meteoroids.

“…2 Almost one hundred years later, the Leonids 1998 outburst was observed from a balloon with modern instruments. 3 Apart from ballon-borne campaigns, meteor storms have been studied in several airborne campaigns, 4,5 but the cost is some orders of magnitude larger than low-cost ballon flights.…”

Atmosphere layers, especially the troposphere, hinder the astronomical observation. For more than 100 years astronomers have tried observing from balloons to avoid turbulence and extinction. New developments in cardsize computers, RF equipment and satellite navigation have democratised the access to the stratosphere.As a result of a ProAm collaboration with the Daedalus Team we have developed a low-cost multi-purpose platform with stratospheric balloons carrying up to 3 kg of scientific payload. The Daedalus Team is an amateur group that has been launching sounding probes since 2010. Since then the first two authors have provided scientific payloads for nighttime flights with the purpose of technology demonstration for astronomical observation.We have successfully observed meteor showers (Geminids 2012, Camelopardalis 2014, Quadrantids 2016 and Lyrids 2016 and city light pollution emission with image and video sensors covering the 400-1000nm range.
