Korotangi (The Dove)
Korotangi (The Dove) The legend of the korotangi is that it came in the Tainui waka as one of the heirlooms which had been blessed by the high priests in Hawaiiki and which in the new country, would ensure good hunting for the tribe. It was said that the Kawhia and Waikato tribes, who descended from Tainui stock, took the korotangi into battle with them, setting it up on a hill and consulting it as an oracle. The "korotangi" can mean "to roar and rush as the sound of water" in either Maori, Hawaiian or Samoan has been used to support the legend that it was bought on the Tainui waka from afar. The expression “Korotangi” is still used as a term of endearment, or as a simile for any object treasured or loved. A mother lamenting the death of a child will, in her lament, refer to her lost one as her “Korotangi.” 1 No doubt the simile has its origin in the above tradition, which also seems to be a fea- sible explanation of the waiata. It certainly explains the reference to the eat- ing of the pohata leaves and the huahua from Rotorua, as well as the allu- sion to the taumata (hill-top or ridge). The Korotangi, Tawhio Throne, and the art work depicting The Lost Child TeManawa and Korotangi, arrived at Turangawaewae Marae on the same day. The Heart of Heaven is in part the sharing of the walk of TeManawa who lives these things, has fulfilled prophesy. Her journey has been documented since 1992 to current. -

The COLOUR of CREATION Observing and Astrophotography Targets “At a Glance” Guide
The COLOUR of CREATION observing and astrophotography targets “at a glance” guide. (Naked eye, binoculars, small and “monster” scopes) Dear fellow amateur astronomer. Please note - this is a work in progress – compiled from several sources - and undoubtedly WILL contain inaccuracies. It would therefor be HIGHLY appreciated if readers would be so kind as to forward ANY corrections and/ or additions (as the document is still obviously incomplete) to: [email protected]. The document will be updated/ revised/ expanded* on a regular basis, replacing the existing document on the ASSA Pretoria website, as well as on the website: coloursofcreation.co.za . This is by no means intended to be a complete nor an exhaustive listing, but rather an “at a glance guide” (2nd column), that will hopefully assist in choosing or eliminating certain objects in a specific constellation for further research, to determine suitability for observation or astrophotography. There is NO copy right - download at will. Warm regards.

President's Message
President’s Message Wow, what a month February has been! LIGO announced, on February 11th, that they had detected and measured gravity waves! What a breakthrough for physics and astrophysics. Dr. Amber Stuver, of LSU and LIGO Livingston, was the speaker at HRPO on Friday, Feb. 19th, during the public talk about this discovery. The guest speaker for the April 11th BRAS meeting will be Dr. Joseph Giaime, LSU professor of Physics and Astronomy, and the LIGO Livingston Observatory head. On December 3, 2015, the European Space Agency (ESA) launched the LISA Pathfinder mission, a space experiment to test and work out the procedures to observe lower frequency gravitational waves (lower than the waves detected by LIGO) emitted by different astronomical sources, such as the merging of super-massive black holes at the center of large galaxies. LISA Pathfinder has started its science mode, testing methods that are to be used in the L3 mission of ESA (a gravitational observatory to measure distortions in the fabric of space-time on the inconceivably tiny scale of a few millionths of a meter over a distance of a million kilometers). April 6th through April 10th is our annual Hodges Gardens Star Party. You can pre-register using the form on the BRAS website. If you have never attended this star party, make plans to attend this one. Clear Skies, and have a good March, John Nagle, BRAS President Canis Major – the Great Dog Position: RA 06 n12.5 to 07 27.5, Dec. -11.03° to -33.25° Named Stars: Sirius (Alpha CMa), “scorching”, “the Dog Star”, mag. -
