The Story of the Icarus Slitless Spectrograph
The journey of the Icarus Slitless Spectrograph - Eclipse observations
After one solar cycle of spectroscopic Eclipse observations during seven solar eclipses, we developed, designed and constructed the Icarus Slitless Spectrograph (ISS), dedicated to capturing the flash and coronal spectrum during totality (and also the spectra of the stars). Icarus spectrograph is used in a variety of laboratory applications.
It was used for the first time during the Total Solar Eclipse of 2006 in the island Kastellorizo, Greece. After many optomechanical improvements is still in use for spectroscopic Solar Eclipse observations during the following total solar eclipses:
- 2008 in Novosibirsk of Siberia, Russia
- 2009 in Tianhuanping - Shanghai of Anji, China
- 2010 in Easter Island, Chile
- 2012 in Cairns, Australia
- 2013 in Mkongo of Gabon, Africa and
- 2015 in Svalbard, Norway
The optomechanical construction of the Icarus Slitless Spectrograph is specially designed for recording the Flash Spectrum during total solar eclipses. The ISS design and construction is based on the prototype which has allready completed a full Solar cycle and is still in use. After processing the data collected during the seven eclipses, two papers have been published on scientific journals (and one is under writing). These results have also been presented in several seminars, lectures, conferences, poster presentations, workshops etc.
The ISS can also be used by night, for astronomical spectroscopy, using a simple equatorial mount, for capturing the spectra of the planets, stars, nebulae and comets. It can also be used for a lot of laboratory and commercial applications, such as light pollution spectral analysis.
