During the annular (87.6%) solar eclipse of May 20, 1966, more than 60 measurements of total ozone were taken with the Dobson ozonespectrophotometer at the University of Sofia, Bulgaria. An analysis of data obtained shows an ozone increase of 25–30 m atm-cm (?? > 2??) at the maximum phase of the eclipse. However, according to the photochemical theory, only ?1 m atm-cm increase should occur during an eclipse such as this. The difference between the theoretical and observed increase of the total ozone may be partly due to the limb-darkening effect. The importance of this effect increases progressively to the maximum phase of the eclipse. When dark-limb correction is applied to observational data, the ozone increase is reduced to 14 m atm-cm (about 4 per cent of the total ozone amount). This increase is as yet unexplained.DOI: 10.1111/j.2153-3490.1968.tb00382.x
  • The results below are discovered through our pilot algorithms. Let us know how we are doing!

    • are too small ( c 1 m atm-cm). If the photochemical interpretation is correct, no increase in the total ozone3 amount could be detected with the measurement methods now in use.
    • Other values for the constants used in the photochemical computations will give u8 another approximation between theoretical and observed ozone increases, showing again our uncertainty in the values of k,, k,, etc., a t the present time.
