June 09 Public Meeting
This month’s public meeting takes place on Wednesday 17th June.
“Solar Observing” by Peter Meadows
The Sun has a significant impact on our planet, it’s atmosphere and magnetic field. Solar activity can be safely observed using small-to-medium sized telescopes via the use of special filters which either reduce light levels to a safe minimum (allowing observation of surface detail and sunpots) or only transmit particular wavelengths of light (such as use of a Hydrogen-Alpha filter for more dynamic solar features like flares and prominences). A selection of observations made by the speaker over the last solar cycle and from other solar observers will then shown, describing the characteristics of solar cycles, the present solar minimum and the start of the new cycle will be discussed. This will lead to the ultimate question of the moment – “Why has the sun been so inactive recently?”.
