NEVER LOOK AT THE SUN DIRECTLY. Please see our Solar Observing safety page at crayfordmanorastro.com/solar-safety/
CMHASD members Jim Burchell, Honor Wheeler and Simon Dawes took the opportunity to observe and image the Sun on Friday 7th July 2023 and below are their super images.
The Sun is very active with many sunspots and one so large it was seen from Mars; yes that is correct – from Mars.
The very large sunspot AR3363 which has just emerged over the Sun’s southeastern limb was spotted by the Mars rover Perseverance several days before we did. On July 2nd, the rover’s mast-mounted stereo camera MASTCAM-Z tilted up to the sky above Jezaro crater and photographed a deep-black dot on the solar disk.
