Hands-on experience in astronomy through practical projects.
This year there will be several projects in different fields of
astronomy / astrophysics / technology. Teams are going to be
assembled according to students' fields of interest. The current
list of our team leaders with their projects is available here:
Suzana Galović: Astronomical spectroscopy
Boris Štromar: Astrophotography
Denis Vida: Croatian Meteor Network - data analysis
Abstract: Croatian Meteor Network (CMN) is currently monitoring
the night sky over Croatia and near surroundings with 30 paired
cameras that enable precise trangulation of detected meteors and
their orbit determination. There has been an ongoing effort of
CMN to produce an automated, scientifically meaningufull,
photometric analysis of detected meteors as well. Recently, it
has been observed that light-curves of detected meteors display
large amplitude and high frequency intensity variations as the
meteor passes through it's brightest phase. These intense brightness
variations could possibly be attributed to meteor's rotation.
It's the goal of this group to try and obtain light-curves of
meteors detected by CMN, analyse their frequency spectrum and
try to determine their rotation rates.

Geophysical observatory - ELF Observations of Ionosphere
Abstract: The main instrument at Tican Geophysical Station is
Schumann antenna which is used to observe Ionosphere at Extremely
Low Frequencies and one of the main goals is detection of ELF EM
waves during meteor showers. Theoretical models predict these signals
but they have never been observed before. Observations were
successfully started recently and the system was automated. In
order to produce quantitative results, an absolute calibration of
Schumann antenna is required. Trivial and simple methods fail at
ELF since antenna length cannot be matched with the wavelength.
The goal of this group is to design a system for calibration and
perform the calibration on the Schumann antenna. Students will
gain knowledge and experience in antenna design and RF electronics
as well as data processing and analysis. Students will learn to use
LabView and MATLAB to perform these. There is also ample scope to
contribute to the development of the LabView code controlling the
observations as well as further automation.
* Minor changes of groups and leaders are still possible and will be fully defined until the end of June.
