Do join ASSA JHB on the hill for a lovely evening of sky and braai. Dress warmly, bring along your meat to braai, your condiments, drinks and salads, anything you need for your meal, hmm… fingers were invented before knives and forks? and  oops, do not forget a chair or ‘situpon’. You may bring your own telescope if you want to.

In the Night Sky

WINDY AUGUST

 

August, a windy mixed up month with signs of many changes after the dormancy of winter. Yet, for astronomers winter has not been dormant. Beautiful night skies have been observed, noted and photographed.

Now there is a slow cool uncoiling and a twist to the new that is to come for spring, summer and autumn.

Still needing to do some work on winter constellations? Look from your zenith westward. Note, Venus and Mars are almost opposite each other at 9pm.

North, northeast and eastward we have the rising of spring and summer constellations and a fresh look at ancient beginnings.

The Universe is, was and always will be. Just a new face on old and divine etchings.
