Colour remote sensing of the impact of artificial light at night (II): Calibration of DSLR-based images from the International Space Station
Alejandro Sánchez de Miguel, Jaime Zamorano, Martin Aubé +6
Nighttime images taken with DSLR cameras from the International Space Station (ISS) can provide valuable information on the spatial and temporal variation of artificial nighttime l…
Balloon-borne video observations of Geminids 2016
Francisco Ocaña, Alejandro Sánchez de Miguel, ORISON team +1
We investigate the observation of meteors with video cameras in stratospheric balloons, overcoming tropospheric handicaps like weather and extinction. We have studied the practical…
XMMSL2 J144605.0+685735 : a slow tidal disruption event
R. D. Saxton, A. M. Read, S. Komossa +6
Aims. We investigate the evolution of X-ray selected tidal disruption events. Methods. New events are found in near-real time data from XMM-Newton slews and are monitored by multi-…
Analysis of the September -Perseid outburst in 2013
J. M. Madiedo, J. Zamorano, J. M. Trigo-Rodriguez +11
We analyze the outburst experienced by the September -Perseid meteor shower on 9 September 2013. As a result of our monitoring the atmospheric trajectory of 60 multi-s…
Low cost multi-purpose balloon-borne platform for wide-field imaging and video observation
Francisco Ocaña, Alejandro Sánchez de Miguel, Aitor Conde +1
Atmosphere layers, especially the troposphere, hinder the astronomical observation. For more than 100 years astronomers have tried observing from balloons to avoid turbulence and e…
First results of the Test-Bed Telescopes (TBT) project: Cebreros telescope commissioning
Francisco Ocaña, Aitor Ibarra, Elena Racero +3
The TBT project is being developed under ESA's General Studies and Technology Programme (GSTP), and shall implement a test-bed for the validation of an autonomous optical observing…
Testing sky brightness models against radial dependency: a dense two dimensional survey around the city of Madrid, Spain
Jaime Zamorano, Alejandro Sánchez de Miguel, Francisco Ocaña +7
We present a study of the night sky brightness around the extended metropolitan area of Madrid using Sky Quality Meter (SQM) photometers. The map is the first to cover the spatial…
Orbits and emission spectra from the 2014 Camelopardalids
José M. Madiedo, Josep M. Trigo-Rodríguez, Jaime Zamorano +9
We have analyzed the meteor activity associated with meteoroids of fresh dust trails of Comet 209P/LINEAR, which produced an outburst of the Camelopardalid meteor shower (IAU code…
Analysis of a superbolide from a Damocloid observed over Spain on July 13, 2012
Jose M. Madiedo, Josep M. Trigo-Rodriguez, Jaime Zamorano +15
A superbolide with an estimated absolute magnitude of -20+-1 was seen on July 13, 2012 over the center and south of Spain. This extraordinary event, which was witnessed by numerous…
The 2011 October Draconids outburst. I. Orbital elements, meteoroid fluxes and 21P/Giacobini-Zinner delivered mass to Earth
Josep M. Trigo-Rodríguez, José M. Madiedo, I. P. Williams +17
On October 8th, 2011 the Earth crossed the dust trails left by comet 21P/Giacobini-Zinner during its XIX and XX century perihelion approaches with the comet being close to periheli…
