Total solar eclipse 4 December 2002

Australian total and annular eclipses for the 21st century

During the 21st century Australia (and adjacent territorial waters) get 10 total, 1 hybrid and 7 annular solar eclipses; whose dates are listed below. Maps for most of these are provided; courtesy of some screenshots of Guide 6. These paths are based on estimated future values for Delta-T, and may shift a few km in the east-west direction when re-calculated with the actual Delta-T value for that year.

The eclipse path is shown in dark green (for total eclipses) or bright green (for annular eclipses). Bordering the path on both sides are ten bands of cyan greens, representing the zones of partial eclipse. The boundaries between the bands represent the 10 percent intervals.

For example, on the 2012 Nov 14 map, the tip of Cape York gets about 90 percent partial eclipse, Melbourne gets a little over 50 percent partial eclipse; and the abrupt western termination of all the bands is where the eclipse is greatest at local sunrise.

Also during the 21st century, many eclipses whose paths miss Australian territory will nevertheless produce partial eclipses here. These are not listed below.

Australian state abbreviations: NSW = New South Wales, NT = Northern Territory, QLD = Queensland, SA = South Australia, TAS = Tasmania, VIC = Victoria, WA = Western Australia.

City eclipses

The last total solar eclipse to cross an Australian state capital was on 1976 Oct 23, when Melbourne was in the path of totality. The next such event is the 2028 Jul 22 total eclipse which will cross Sydney. But if atmospheric refraction is favourable and the sky is clear, then Darwin might see the totally eclipsed sun of 2012 Nov 14 on the horizon at sunrise.

Although the Australian landmass is crossed by eclipses several times per century (on average); any specific place may have to wait a very long time between total or annular eclipses. For example, Adelaide is currently in a five century long eclipse "drought", as shown in this list of Adelaide's first 2200 years of eclipses:
