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

Night Skies for November.

 

Change is constant and most constantly, Gauteng Astronomers are affected by our summer weather patterns. Over and above that, astrnomers are people who never give up. Their desire to know more, their desire to see more, is surely the grit that makes them try and try again. Changes will come but without a doubt we will continue searching and seeing with passion.

For the month of November we have  Saturn in the west, Mars and Venus in the East and if we are lucky, a fast last gaze at Jupiter.

With regard to constellations, all our known favourites are back in their summer places and all around them are the beautiful nebula and galaxies, so beautiful and so mystical, ready to amaze us night after night.

May the light of stars: Aldebaran, Betelgeus, Sirius, Canopus, Achernar, Formalhaut and more shine brightly upon all.

Looking Upward!
