Goal
Creation of databases of solar EUV images and spectra obtained in the SPIRIT experiment (August 2001 – December 2005, maximum and declining phases of the 23d solar cycle) and TESIS experiment (launched 30 January 2009 for at least 3 years – from minimum to maximum of 24th cycle) available for all SOTERIA participants to use in the implementation of the project.
Successes
The TESIS EUV telescope/spectroheliograph was successfully launched on January 30,2009. The instrument has 3 telescopes for Fe 132, Fe 171 and He 304 A spectral bands, Mg XII spectroheliograph and XUV spectrometer for 280-330А band. All the TESIS instruments were successfully calibrated in February 2009 (during first month of flight). On Febryary 20, 2009, the first images were transmitted to the Earth: http://www.tesis.lebedev.ru/info/TESIS_first_data.php.
Starting from Febryary 20, 2009, TESIS provides continuous monitoring of the Sun in 6 EUV channels corresponded to solar transition region, corona and high-temberature plasma of solar flares. In total, the following number of images were obtained till October 2009:
- Transition region of the Sun in the line HeII 304 A (T ~ 80 000 K): 32 000 images;
- Solar corona in the line FeIX 171 A (T ~ 0.8 MK): 36 000 images;
- Extended solar corona in the line FeIX 171 A (T ~ 0.8 MK): 7 000 images;
- High temperature plasma in the line MgXII 8.42 A (T ~ 8 MK): 12 000 images;
- High temperature plasma in the line FeXXIII 132 A (T ~ 10 MK): 10 000 images;
- EUV solar spectra of the range 280-330 A (T = 0,05 - 10 MK): 3 000 images;
- EUV solar corona (0.01-5 solar radii): 3 000 images;
The access to TESIS daily data is open for registered users in the site of project: http://www.tesis.lebedev.ru
Exceptional Discoveries
TESIS provided data of exceptional quality on the development and dynamics of eruptive processes in the solar corona. In 2009, during a deep minimum of solar activity, about a dozen giant eruptive prominence and coronal mass ejections were recorded in wonderful detail:

Progress so far
LPI
The SPIRIT database is supported at the address: http://spirit.lebedev.ru. The TESIS experiment page is supported at the address: http://www.tesis.lebedev.ru (currently only in Russian). The TESIS database is initiated in the course of the commissioning and calibration stage of the experiment and will be available to SOTERIA users after the start of routine exploitation. The data are stored in FITS format compatible with most of currently operating solar instruments. Description of the data format and processing levels will be distributed soon.
