During discussions concerning a previous posting another aspect of the video of Ms. Pisciotta became the subject of the conversation. For one familiar with the summit and the position of the features, the claims seem unlikely, something worth a closer look.
If you listen to the clip Ms. Pisciotta makes a very emphatic claim… That the construction of TMT will block the view of the Sun as it makes its annual pattern of sunsets along the horizon.
While I am singling out Ms. Pisciotta a bit here, she is a key figure in the opposition. She is a leader of Mauna Kea Anaina Hou, the most active opposition group and a primary participant in every significant legal case on the issue for the last several decades.
How can we examine this claim? From winter solstice, to equinox, to summer solstice, the position of sunrise and sunset changes significantly. This cycle has been tracked by shamans and priests for millennia, using the pattern to set the time of planting or religious ceremonies.
