Current and upcoming events

  • 2016 September 16 – Penumbral Lunar eclipse . Note that as this is a penumbral eclipse, only the outer Earth shadow will cross the Moon and as a result the eclipse may not be obvious to the naked eye.
  • 2016 October 3 – Moon is near Venus in the evening sky
  • 2016 October 6 – Moon is near Saturn in the evening sky
  • 2016 October 8 – International Observe the Moon Night. ASSA is currently looking at various initiatives for this evening, including the possibility of live streaming.
  • Orionids Meteor shower. This meteor shower is typically active from 2 October until 7 November, with the peak meteor rate being observed about the 21 October and best between midnight and 4.00am. Unfortunately conditions are not good this year for observing this shower.

Recent Events

  • The partial eclipse of the Sun on Thursday,  September 01 2016. This was the only solar eclipse visible from southern Africa this year. In fact, it was visible from almost anywhere in Africa (except the very northernmost parts), and seen from central Africa and Madagascar it would be annular. This rare event was a wonderful opportunity to witness the solar system in action, as the Moon slid in front of the Sun. Using simple materials, the progress of the eclipse – which lasted more or less 2 hours – could be watched, shown to family and friends, and shared with the world. Further information is available on the ASSA Eclipse 2016 page
  • Conjunction of Venus and Jupiter August 27th 2016. The separation of the pair on the 28th August 2016, at 18:49 (SAST) was 15′ 07.2” (just over a quarter of a degree). At their absolute minimum, the two planets had a separation of 4′ (arcminutes) at 21:47 (SAST), but would have been below the horizon for South African observers at this point.
  • Past events are archived on the ASSA website archive.
