abstract = {One of the systems employed by the
SPanish Meteor Network (SPMN) to perform a continuous
monitoring of meteor and fireball activity is
based on high-sensitivity CCD video cameras. These
devices have been commonly used for the determination,
for instance, of radiant, orbital and photometric
parameters [1, 2, 3]. Besides, they are also suitable for
meteor spectroscopy [3]. When properly configured,
these cameras are also able to work under twilight conditions.
This is one advantage with respect to slowscan
CCD systems, as this allows extending the operation
period to some minutes before sunset and after
sunrise. Here we analyze a double-station sporadic
fireball recorded in the morning twilight of July 7,
2011.},
