Default For the Astronomy Buffs

On August 27 just after sunset in the western sky, the Venus and Jupiter Conjunction should be clearly visible before both set.

From the left, Mercury then Jupiter an then Venus will al be visible just above the Western Horizon, with Venus being the largest of the three. Binocs will help as well as a clear view of the horizon.

Then on September 1, a partial eclipse of the sun will be visible even as far South as Cape Town. 20% in CT, about 50% in Pretoria.
The greatest Eclipse is at noon over Tanzania.

The eclipse is known as an Annular Eclipse because the moon will not completely blot out the sun, leaving a ring visible around the moon. We will not be able to see this in South Africa.

best viewing times will be some where between 10:00 and 11:00 and will last for a very short period of less than 3 minutes.

See many sources on the web form more details, plus Google Earth will gibe you a more accurate time when this will happen for your location.

the next Eclipse (total) occurs over the USA on August 21 2017.

Default The Supermoon!

Today is the day when the moon will be closet to earth since 1948. It also happens to co-inside with full moon, making the moon quite spectacular just after it rise in the East.

Full moon has just passed (at 15:52 for JHB). Moon rise will be at about 18:32.

Rather much ado about nothing. Didn't look all that spectacular to me...or very different to normal. Maybe slightly larger, but not really anything to get all worked up about.

Unless you're an extreme surfer apparently. They say the waves were going to be pretty large last night...but I have no idea if that was so or not.

Yes they were in quite a few places. Combined with the weather effects some places on the coast had some pretty unusual tides and large waves to contend with.

Astronomy Buffs are always excited about planetary lines ups and unusual "once in a lifetime events"

NASA has announced an important press conference about a new exo-planet (planet around another star other than our sun).
tomorrow (Wed.) @ 13:00 American Eastern Standard Time which will be 20:00 our time.
Doubt it will be live on any of our news channels, so we'll have to find online coverage.

What can it be...

My guess since it's important - the sought after main discovery of a planet similar to Earth!!
But I'm an optimist, so maybe not...


News for exo-planet



The Independent
Nasa announces major press conference on a 'discovery beyond our solar system' The Independent - 4 hours ago
The event will see the revelation of major information about exoplanets, or
planets that orbit stars other than our sun, according to a release.

NASA to make big exoplanet announcement NEWS.com.au - 12 hours ago

Nasa calls major news conference to reveal 'discovery beyond our solar system' that could aid quest for alien life The Sun - 5 hours ago

EDIT:
The Independent says this;
"Exoplanets are the major hope for life elsewhere in the universe, since many have been found that resemble our own Earth and could have the building blocks of life. More of them are being discovered all the time."

The part I've coloured is nonsense - last I heard, so far there have been a few comparable features found, but nothing really coming close to an actual Earth II.

Don't miss my edit above.


More food for thought, from the second article;

However US tech publication CNET claims to have seen the findings and said; “Let’s just say it could very easily provide us with new settings for many future works of science fiction.”

Default ISS long visible pass tonight

If you are lucky enough to have clear skies there is an around a 6 minute overhead pass of the ISS tonight from 19:45.
This is the best possible ISS viewing for some weeks to come.

The skymap attached is for Pretoria and results will differ slightly for other regions

Here is the URL if you want to run the app. You should have the latest Java version installed and will need to grant the app appropriate permissions in your Java setup.

https://spaceflight.nasa.gov/realdat.../JavaSSOP.html

Be patient for it to load.

Cheers, K

The weather is rater unlikely to clear over Gauteng, so there is a slim chance of being able to see this pass.

Had plenty of bad luck lately with trying to see the ISS.

The only completely overhead pass over the farm in the Karoo recently was also a disappointment as that night is was completely overcast.
