It was an extremely busy & interesting day. Several members of the public took the opportunity to drop by for a chat, observe the current activity on the surface of our nearest star the Sun using the 3 telescopes that were on display and to view our various display boards showcasing the societies activities. Our 3D photographs & the planet game also proved to be very popular too!
Safe views of the Sun were offered by various CMHASD members that helped throughout the day using ‘Anita’ one of the societies Dobsonian telescopes built by members Steve Floodgate and David Grist (see Building Dobsonians) whilst member Jim Burchell offered safe views through his refractor. Both of these telescopes were showing white light views of the sunspots currently visible on the Sun’s surface.
Member Diane Clarke offered safe views of the sunspots on the Sun too as well as the Sun’s various prominences and surface detail with her Ha (Hydrogen alpha) line telescope, see the 2 photos below.
Both images captured an absolutely massive prominence on the Sun at the 11 O’Clock position; this wall of plasma was more than five times taller than our entire planet Earth! There were also prominences captured at the 1,2,6 and 10 O’Clock positions too in the images.
NEVER LOOK AT THE SUN DIRECTLY. Please click here for solar observing safely.
