1959 - ASSA Bloemfontein Centre

Die Bloemfontein Sterekundevereniging is vanjaar 50 jaar oud! Gaan dwaal gerus in die argiewe rond om te sien wat die afgelope halfeeu gebeur het.
Hier is `n kort inskrywing van die eerste vergadering:

1959 - ASSA Bloemfontein Centre

March 18th, 1959
A meeting was held at the Technical College, Bl
oemfontein, on March 18th, 1959, under the auspices of Dr. H. Haffner, at which it was decided to seek the approval of theCouncil of the Astronomical Society of Southern Africa to the formation of a Bloemfontein Centre of the Society. Dr. C.B. van Wyk was elected Chairman, Mr. N. Lincoln Secretary. Dr. Haffner & Mr. M. J. Bester
were elected to the Committee. It was decided that the next Meeting should be held at the Boyden Observatory on April 20th, at 7.30 p.m.

Those present at the Meeting enjoyed a talk by Dr. Haffner on "The Moon", illustrated by lantern slides. An article in "The Friend" of 19 March 1959 reads as follows: Astronomy society branch Dr. C.B. Van Wyk, professor of applied mathematics at the University of the Orange Free State, was elected chairman at the inaugural meeting of the Bloemfontein centre of the Astronomical Society of Southern Africa last night. Dr. Haffner and Mr M.J. Bester were elected to the committee, with Mr. Lincoln as secretary. There were about 20 foundation members. After the meeting Dr. Haffner gave an illustrated talk on "The Moon". He confined himself to the more technical side of the subject, as he considered he said, that enough had already been said about the more imaginative side.

The next meeting of the centre will be held as an observation evening at Boyden Observatory, Mazelspoort, at 7.30 p.m. on April 20. An open invitation has been extended to anybody interested in astronomy to attend the centre's meetings.

ISS - Visible Passes over Bloemfontein

Dit is elke keer `n wenner!

Wow! Take a look at this image captured by award-winning French astrophotographer Thierry Legault. The visible detail of the shuttle and parts of the International Space Stations is absolutely amazing! If you remember, Legault also took images of space shuttle Atlantis and the Hubble Space Telescope transiting the sun back in May during the HST servicing mission.

Legault is an engineer who lives near Paris. He started his digital imaging in 1994, and currently uses a SBIG STL-11000M CCD camera with AO-L system that is equipped with large and narrow band filters. He also uses a reflex Canon 5D, webcams from Philips as well as Astrovid video cameras.

He has written two books: "The New Atlas of the Moon" with Serge Brunier (Firefly) and "Astrophotographie" (Eyrolles), and is featured in a new book by Robert Gendler, "Capturing the Stars: Astrophotography by the Masters."

Southern Sky News for 2009 August

Augustus is Jupiter se maand. Nie eens Mars wat so "groot" soos die maan gaan word, gaan die ou grootte se donder steel nie. Oops! Nou is almal weer ontsteld. Nee! Nee! Nee! Mars gaan nie so groot soos die maan word nie. Jupiter en sy mane is die hele Augustus-maand van vroeg tot laat sigbaar. Die mane is nou wel net sigbaar met `n kragtige verkyker of klein teleskoop. Op 14 Augustus is die Jupiter in opposisie as die aarde direk tussen hom en die son is. Dit is dan ook op sy helderste.

Gaan loer na die impakkol op Jupiter

Hierdie is `n voorstelling wat met Skytools 3 geskep is soos gesien deur `n 11" duim teleskoop, 29 Julie om 05:14.

Gaan loer gerus deur jou teleskoop hoe die impakkol nou lyk. Ek het hierdie tye op Auke Slotegraaf se blog raak geswerf. Auke Slotegraaf is die huidige Direkteur van die ASSA* Dieplug waarnemingsafdeling. Besoek Auke se Sterrekunde webtuiste

Bydrae deur Amateur Sterrekundiges...

Goeiedag Vriende
Sterrekunde is een van die min displines in die wetenskap waar amateurs nog belangrike bydraes kan maak - gaan kyk gerus op APOD by http://antwrp.gsfc.nasa.gov/apod/astropix.html na die belangrike ontdekking onlangs gemaak deur 'n amateur sterrekundige in Australië: 'n nuwe impak-letsel op Jupiter.

As jy nie by die link kan uitkom nie, hier is die foto wat geneem is van Jupiter, met die impak-letsel 'n swart merk net onderkant die boonste pool van die planeet.



Moenie die amateurs afskryf nie - word eerder een!!!!

Groete en "clear skies"!!

How do you sneeze in a spacesuit? 'Aim well,' astronaut tells YouTube questioner


By Mike Schneider, The Associated Press

CAPE CANAVERAL, Florida - When it comes to sneezing in a spacesuit while in the void of space, it is best to aim well.

That's the advice lead spacewalker David Wolf offered Tuesday while answering one of the questions posted on YouTube for the crew of the space shuttle Endeavor.

"I've done it quite a few times, most recently yesterday," said Wolf, who led the mission's second spacewalk Monday and was set to go on a third spacewalk Wednesday. "You learn in training, and I don't know how to say this, aim well. It can mess up your view and there is no way to clear it."

Land on the Moon in Google Earth

To celebrate the 40th anniversary of the Apollo 11 Moon landing, Google has launched a new feature: the Moon in Google Earth. You can now use Google Earth to explore, fly around and search the Moon. Google was able to get several astronauts to participate in this new feature, and you can get tours of landing sites, narrated by Apollo astronauts, view 3D models of landed spacecraft, zoom into 360-degree photos to see astronauts' footprints and watch rare TV footage of the Apollo missions. The hi-resolution views of the Moon were developed in collaboration with NASA Ames Research and JAXA. It's loads of fun and provides an historic perspective as well as a look to the future of lunar exploration. If you already have Google Earth 5.0 on your computer, just click on the tab on the top toolbar that has a picture of Saturn, and click on Moon. If you click on the Apollo 11 flag, you can zoom in on that location and take a tour of the first landing site on the Moon! What a great way celebrate the 40th anniversary. Enjoy!
