The concrete floors have been cleaned and stabilized in the Astronomical Study cellar and the Dome Room. The Pillar Room floor will need warmer temperatures as the epoxy we are putting on the floor cannot cure properly. This is because the floor of the Pillar Room sits directly on the ground – there is no cellar beneath– and the pillar for the telescope located in this space goes directly down into the ground. This is done so that if there is any movement in the building, the telescope itself will not move or shake. While we wait for that final treatment of the Pillar Room floor, the electrician has moved in. He has replaced the very old wiring – but kept the original switch knobs for the glass plates built into the bookshelves. These glass plates are from the 1920s – most were taken at the Maria Mitchel Observatory. We have restored push button light switches – they more than likely had those as we had them in our former Science Library – now Research Center – and bronzed switch plates that are more in keeping with the time period. We have removed the 1980 track lighting and placed four larger ceiling lights in their place. The Study never had ceiling lights or sconces – just task lighting – but we do need better lighting than that so we located some lighting that is in-keeping with the period and the use of the building. Other switches and lights are being updated – the wiring in particular. Pen Austin will some come in to make a few small lime plaster repairs from the track lighting – interesting construction that revealed itself upon taking down the track lights. Lime plaster, concrete, chicken wire, wood, and some much older looking nails than I expected for 1922. A thank you to Brian Connor Electric and to Elizabeth Markle for help sourcing the lights.

About International Dark Sky Week: International Dark Sky Week is a global initiative of DarkSky International to celebrate the dark and natural night sky, raise awareness about light pollution, and promote the use of environmentally responsible outdoor lighting during the week of the new moon in April each year. About the Nantucket Conservation Foundation: The Nantucket Conservation Foundation owns, protects, and stewards over 9,000 acres of land and coastal shoreline, conserves Nantucket’s rare and significant natural resources, and engages in impactful ecological research to inform resource management and further our knowledge of Nantucket’s unique ecosystems and species. Through conservation, education, and stewardship, the Foundation aims to maintain Nantucket’s unique ecosystems and natural beauty for future generations. About Nantucket Lights: Nantucket Lights is an all-volunteer citizen advocacy group committed to preserving and protecting Nantucket’s nighttime environment and heritage of dark skies by raising awareness about light pollution on the island and advocating for environmentally responsible outdoor lighting. About the Maria Mitchell Association: The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first female professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages. ###
