Lunar Event 27 July 2018: 

The Johannesburg Centre of ASSA hosted a very successful eclipse viewing evening.  However we ran into some unfortunate problems which were very difficult to control.  Firstly we did not expect that so many visitors were going to arrive at the observatory.  This lead to parking problems in the nearby residential area and also people that could not attend.  With this said, we would like to sincerely apologize that we could not accommodate all the visitors, and to the residents who were inconvenienced.  In the future we will be pro-active and make sure that we as the society have all communications and the necessary equipment available that might be needed.

The NASA Dawn Mission used ion propulsion to explore the two largest bodies in the main asteroid belt, Vesta and Ceres, unlocking the secrets of these two deep space destinations. The mission will end this fall, when the spacecraft runs out of hydrazine, which keeps it oriented and in communication with Earth. Watch & learn more: https://go.nasa.gov/2QcZZba

In the Night Sky

SEPTEMBER

 

Shades of light and shades of dark.

Orion comes up crisp and stark.

It is time for us to visit anew, all the wondrous things that meet the eye, we find most in our summer sky.

Farewell Scorpius until upon return we re-visit Antares, the star of gold with its green companion old.

There is such a buzz about the visit to the sun, many satellites and scientific fun.

Has Titan got water? Jupiter has 12 more moons. Mars raged with wind and gave a poorly sight. Yet still, we love the night.
