Our speaker this month is Thomas Deere. Tom holds a BA in Anthropology, BEd, specialists certification for teaching Iroquoian languages and Environmental Education.  He has a deep interest in researching the astronomical knowledge of the Hodinǫhshǫ́:ni, and for many years has been interviewing elders, and investigating anthropological native language texts to identify astronomical wisdom. With this traditional knowledge, he helped to develop a show for W. J. .J. McCallion Planetarium at McMaster University based on the Hodinǫhshǫ́:ni origin story of the Ursa Major (Big Dipper) constellation.  On Friday, Tom will be discussing the origin stories of the Big Dipper and the Pleiades constellations as well as well as the ceremonial calendar of the Six Nations’ people.

Our speaker this month is Dr. Samanthan Lawler.  Dr Lawler is a professor of astronomy at the University of Regina in Canada. She completed degrees at the California Institute of Technology, Wesleyan University, and the University of British Columbia, followed by postdoctoral fellowships at the University of Victoria and NRC-Herzberg Astronomy and Astrophysics Research Centre.  She studies the orbits of Kuiper Belt objects as well as light pollution from satellites.  She has been advocating for regulation of satellites as her research telescope data and her dark prairie skies have increasingly filled with bright satellites over the past several years, and recently helped to publicize two separate SpaceX debris falls that occurred in Saskatchewan.
