Map F.2: Astronomy Reserve in the <strong>Northern</strong> <strong>Cape</strong> with the core site of SKA (Source: SKA Africa,<br />

www.ska.ac.za)<br />

<strong>The</strong> location of the candidate core site in the Karoo was chosen because of the following attributes<br />

(SKA Africa Brochure, 2011) 65 :<br />

a) <strong>The</strong> radio frequency interference (RFI) environment is intrinsically quiet because of the<br />

remoteness of the site and the shielding effect of the flat‐topped hills surrounding the<br />

area.<br />

b) <strong>The</strong> area is far from centres of economic activity and has a very low and decreasing rural<br />

population.<br />

c) <strong>The</strong> climate is benign with no extreme weather conditions (e.g. high winds or extreme<br />

diurnal temperature variations).<br />

d) <strong>The</strong> site is at a 1 000 metre elevation with a flat topography.<br />

e) <strong>The</strong> water vapour content in the troposphere is low.<br />

f) Despite being remote, the area is well‐served with essential infrastructure, including all‐<br />

weather roads and national grid electrical power, and is easily accessible from major<br />

settlements.<br />

g) Required land, labour and services available and very affordable.<br />
