Rainbow “Like A Building Block” Seen In Vicinity of Unwin Radar At Awarua

By Wayne Muntz of Riverton, May 29, 2013.

Approximately one year ago, while driving to Invercargill to catch a 7am plane, I was looking south toward Awarua/Bluff on a very dull and dark morning, with the driving lights on. There was a 3-colour rainbow, shaped like a building-block, that was perpendicular to the ground. It was purple/reddish yellow and blue. Because of the low heavy clouds it disappeared into them.   It was not a natural rainbow.

The Unwin Radar is located at Awarua, 10 minutes north of Bluff, so I surmised that it may have been the cause of this unnatural effect.  I then began researching the phenomenon. 

What I witnessed looked like this below, except it was perpendicular to the ground.

This pictures below of the colourful sky was taken looking NE of Invercargill from Riverton river mouth. Note that it is not a natural looking rainbow and looks similar to the one mentioned in my previous post coming from the Unwin/Awarua location, which is out of sight 90 o to the right or SE, 30 minutes travelling time.  Heavy dark clouds, a hint of sunlight otherwise not a natural rainbow day….so my thinking is the Unwin Radar has capability of producing these fields/pulses well away from its location.

The Unwin Radar is a scientific radar array at Awarua, near InvercargillNew Zealand

Unwin is part of the Super Dual Auroral Radar Network (SuperDARN), an international radar network for studying the upper atmosphere and ionosphere that operates in the High Frequency(HF) bands between 8 and 22 MHz.

The radar and associated research provides greater understanding of atmospheric weather, to assist with weather prediction, prediction of telecommunication interference and provide a better understanding of the effects of atmospheric magnetic fields on power grid management.[1]

The facility is operated by La Trobe University and was named after Bob Unwin, a pioneer in auroral radar research,[2] who first proposed the concept behind the project in the 1960s


Bursts of short-wave radio pulses are transmitted from the radar in a southern arc that includes theSouth Magnetic Pole. The ensuing reflections from micro-meteorites, the ionosphereocean andaurora are detected at the station and resolved there.

The TIGER-Unwin is a monostatic, pulsed radar that operates in the 8 MHz – 20 MHz range. The transmitting antenna consists of an array of 16 log periodic antennas.

  • These antennas form a narrow beam ~4 degrees (at 12 MHz) that is swept across the radar footprint in 16 steps (one step per antenna array).
  • In the vertical direction the beam is ~30 degrees with a maximum in the range of 15 degrees (at 20 MHz) to 35 degrees (at 8 MHz).

An additional four antennas placed some distance behind the transmitting array. These antennas are used to form an interferometer receiving array that measures the elevation angle of echoes. In the standard operation mode the radar uses frequency hopping where the transmission frequency changes to accommodate changing ionospheric conditions. This frequency hopping is done by ongoing scanning the frequency band to determine automatically which channels are free of interference and provide the best coverage.

The data from Unwin is transmitted back to La Trobe University where it is made available over the Internet to users. The Unwin Radar and its counterpart at Bruny Island in Tasmania form theTasman International Geospace Environment Radar (TIGER).[1]

The Southland region is regarded as an ideal location for such a facility because of the southerly aspect, low radio noise and unobstructed horizon.[1]
