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 in January

 

We have travelled the Earth and had such fun. Where ever we were we might have found the sun or the pot of gold at the end of a rainbow!

Nothing will compare to sharing our nights with the heavens above.

December nights took us through flights of stars’, but in January, we will see Mars!

Before Sunrise on the 7th of January  draw an imaginary line from the sunrise point on the horizon, there you will see Mars, Jupiter and Mercury all in a line.

Have a look at the brightest star, Sirius, see if you can draw Canis Major.

Puzzle over the tiny misty dipper, Pleiades, also known as the Seven Sisters.

Have fun and enjoy our January Sky.
