CTARC Pictures of SAAO Meeting 2/2 - 28 Feb '15

Report - Photos Batch One  - Photos Batch Two

After the picnic, at around 19h00 we moved inside into the SAAO lecture theatre and Ruby kindly gave us a talk on the Meerkat and Square Kilometer Array radio astronomy projects. It was very, very interesting. Ruby deftly answred a number of texhnical questions about the project in particular, and radio astronomy in general.

After that talk finished around 19h30, the formal SAAO lecture and slide show took place. Those who wanted to sit in and listen to that could, while others had the chance to see the telescope itself and the adjacent Astronomy Museum.

We discovered that the floor could be raised to meet the telescope's eyepieces!

Here are some photos of the CTARC excursion to the SA Astronomical Observatory in Observatory, Cape Town on 28 March 2015. The afternoon started at around 18h00 with a picnic held on the patio outside the SAAO lecture theatre. It was a pleasant, sociable late afternoon before the lectures began at 19h00

the function of which is sometime mysterious!

prevented us from observing stars or planets later on.

CTARC Report on February Meeting - 28 Feb '15

Report - Photos Batch One  - Photos Batch Two

The CTARC met for an extraordinary external meeting at the South African Astronomical Observatory, in Observatory suburb, on 28 March 2015 at 18h00.

It really was an enjoyable, sociable event. First of all we gathered on the southern side of one of the lecture halls, under a covered awning, to hold a picnic as the sun went down.

The wind, which had started off rather fiercely, was not too much of an issue even though we were outside.

At about 19h00, we cleared the tables and trooped indoors to the lecture theatre. There we were introduced to Ruby, a most knowledgeable lady who gave us a fascinating slide show on the various Radio Astronomy projects - the Meerkat and Square Kilometer Arrays - that are being built (and in some cases, already being used for scientific research) at Carnarvon in the Karoo. We had the opportunity to ask her questions, which were most adequately answered.

At 20h00, the main meeting of the South African Astronomical Association's Cape Town branch took place. Some elected to stay for this interesting meeting. Others were given the chance to take a look at the Observatory's main telescope.

Adjacent to the main telescope chamber is a fascinating museum, full of astronomical equipment, chronometers, models of the large SALT telescope at Sutherland, and other interesting displays. The main telescope is housed in a typically domed observatory building to the East of the main office building. It has a few tricks up it's sleeve! In order to reach the eyepieces of the instrument - a beautiful refractor telescope from the turn of the century - the entire floor in the observatory chamber can be raised up or down!

Sadly, the prevailing cloudy weather prevented us from seeing Saturn as expected, but there will be other opportunities further on. What we did get shown, though, was a bucket full of rare Leopard Toads, who are collected in a bucket each evening (and later released) by a kindly staff member, so that they don't get squashed by visiting vehicles...

The CTARC is hugely grateful to Ruby and the South African Astronomical Observatory for providing us with such an interesting evening.

Photos of this event are found in Batch One and Batch Two.

CTARC Forthcoming February Meeting - 28 Feb '15

The CTARC February Meeting will be held on Saturday, 28 February, and ​it ​will be something different this time:
Start time is 18h00 at the ​ Cape Town Observatory (Next door to the River Club off the Liesbeek Parkway in Observatory suburb.)​

Bring your family, friends and your own picnic and refreshments and have a fun-filled evening. While the weather forecast for Saturday predicts that it will be warm (28 degrees at midday), it will cool down later on and may get windy. Remember to bring a blanket  or ground sheet for your picnic area.

After the picnic on the lawns,  as the sunset fades, there will be a short (about 30 minutes) talk by the Observatory staff, then we will have a tour of the Observatory followed by a chance to look through their telescope in the hope we can see Saturn, weather dependent. If we can see it, it's apparently a sight one won't forget.

Do join us for this really special opportunity.         

Due to limited space inside the Observatory we need to give them a approximate amount of folks attending. So please let Anne know by e-mail if you are attending before Friday 20th February on email:   anne.bareham@gmail.com.
