The 1999 ozone hole covers virtually all of Antarctica with total ozone values still declining at around 2.5 DU per day. The outer margins of the hole currently form a rough heart shape with the axis of the heart aligned towards South America.
Lowest values cover a broad area offset a little from the pole towards the Atlantic Ocean.
Total ozone values at Halley are declining at around 2.6 DU per day. Mean total ozone values fell from around 220 DU in late August to around 150 DU in mid September, then rose briefly to reach 200 DU on September 23 rd when planetary wave activity brought the edge of the ozone hole close to the station. This is the highest ozone amount at the station in the last 10 days of September since 1990. Measurements made at the start of the season are of lower accuracy than in mid summer due to the low solar elevation or use of moonlight.
