The Gibbston 2025 astronomical almanac

This calendar shows the best days in blue for evening stargazing at Antimony Observatory in the Kawarau Gibbston Dark Sky Park.  

 

Each "blue day" has at least 1 hour of astronomical night (defined when the sun is at least 18degrees below the horizon) and there is either no moon in the sky, or its illumiunation is less than 30%.

 

The start of astronomical night is given for the 15th of each month. 

 

Green days are when the clocks go back/forward.
