Results of the analysis of the Comet Halley spectrophotometry,which has been carried out by H.K. Nazarchuk in 1985 with the
TVscanner of the 6-meter telescope (SAO, Russia) are presented. Timevariations in the intensities of the CN, CH, C2 and NH2bands were investigated using the series of spectra obtained inthe spectral region λλ=410÷ 510 nm. Theauto-correlation functions
for all the bands, thecross-correlation functions for C2 lines and their Fouriertransformations are calculated to determine the frequencies andperiods of the variations. A possibility
is considered thathigh-amplitude fast variations of spectral lines in Comet Halleyare caused by solar flares. The daily numbers
of solar spots andproton fluxes with energies of more then 1 MeV are compared withthe spectral variations of these lines.
It is shown that in theobservation periods the comet was projected onto an active regionof the Sun, but, among all the kinds
of solar activity, mainlythe solar proton flux with energies less than 4 MeV coincides intime with fast intensity variations
in the spectral lines. Analgorithm of cross-correlation analysis of discrete samplingseries with gaps is built, and average
cross-correlation coefficientsare calculated. 相似文献
