Fluctuation in ozone column over Ahmedabad during the solar eclipse of 24 October 1995



A solar eclipse occurred over Ahmedabad, India (23°N, 72°E) on 24 October 1995. We measured the vertical column abundance of ozone during this event using a Dobson spectrophotometer. We found that a sharp fall in the ozone column began from its normal value ∼15 minutes before the maximum obscuration (MO) of the sun, followed by a sharp rise ∼10 minutes after the MO. About 15 minutes after the MO, ozone column returned to normal values, but a wavelike fluctuation was still seen.
