Mansfield & Sutton Astronomical Society

Welcome to the Mansfield and Sutton Astronomical Society. We are a non-profit making registered charity dedicated to furthering interest in astronomy within the local community.

Forthcoming Events

13 Aug 2016Solar Observation Day

Summer Solar Events

We will be holding a Solar Observation Day on Saturday 13 August, from 11am to 5pm. Come along and view our nearest star through our specially filtered telescopes. There will be a chance to see sunspots, prominences, flares, and other solar activity. There will also be an opportunity to listen in to the Sun's activities through our radio astronomy equipment, Sun themed lectures throughout the day, and free fact sheet handouts to take away. Society members will also be on hand to answer any questions you may have.

Admission is free (donations welcome), but under 16's MUST be accompanied by an adult. On site parking and refreshments available. Please note that all viewing is weather dependent and the event may be cancelled at short notice.

Public Open Evenings

During Autumn and Winter the society holds public open evenings once a month.

We do not hold open evenings during Spring and Summer because the night sky doesn't darken sufficiently.

For more information about our open evenings, including next Autumn and Winter dates please see our Public Open Evenings page.

"The Night Sky" Evening Course

The course run by the members of the Mansfield & Sutton Astronomical Society covers all aspects of modern astronomy, with a bias towards hands-on practical sessions whenever the weather permits.

Dark Skies

The expansion of Ashfield and Mansfield over the years since our observatory opened has substantially reduced the quality of night sky viewing and MSAS has long been an advocate of keeping our skies as dark as possible. Astronomy is a popular pastime enjoyed by many local people and the members of our society but there are precious little dark sky sites in our locality.

We are supporters of the British Astronomical Association's Commission For Dark Skies and the Peak District National Park Authority's Dark Skies project, and advise local business about efficient exterior lighting to reduce light pollution and save money and energy.

We have also campaigned against proposals for substantial housing development on greenbelt land near our observatory, and a large sand quarry within 3/4 mile of our site due to the impact we believed these would have on light pollution levels.

Society Patrons

The society is pleased to count the 13th Astronomer Royal Professor Sir Francis Graham-Smith F.R.S. and Professor Michael R. Merrifield, from the University of Nottingham School of Physics and Astronomy as its patrons.

Professor Sir Francis Graham-Smith held the position of 13th Astronomer Royal from 1982 to 1990, and also officially opened the Sherwood Obervatory in 1986.

Mike Merrifield primarily studies the properties of nearby galaxies using telescopes at radio, infrared, optical and even X-ray wavelengths.
