Solar ultraviolet flux measurements in the biological band at 290-320nm have indicated a sharp increase in the ground reaching solar ultraviolet total flux during the recovery phase of the 24 October 1995 solar eclipseevent.The flux values came back to their normal control day value withinabout two hours after the total recovery phase of the eclipse.The solar fluxchanges at the visible and near infrared wavelengths did not show anysuch increase in flux except at 600nm,which is in the Chappius band forozone absorption.The observed changes indicate that the increase in theflux could be due to a decrease in the atmospheric columnar ozone.Froma numerical calculation it is inferred that a 4.6% decrease in ozone couldproduce the observed UV flux increase.
