Total Solar Eclipse, Flash Spectrum, Spectral Line

Scientific paper

The flash spectra in the HeI D3 line were obtained during the 2008 total solar eclipse. This paper describes the instrument and the calibration of the obtained flash spectrum, and presents our initial results. The average integrated intensity is E ave = 8.13 × 1013 erg·cm-1·s-1·ster-1 at h = 1100 km, which confirms that the HeI D3 emission is negatively correlated with the solar activity. The surface brightness reaches a maximum of F ave = 8.25×105 erg·cm-2·s-1·ster-1 at about h ≈ (1290 ± 75) km and then decreases exponentially with height when h > 1800 km with an exponential index β = 1.63×10-8 cm-1.
