Solar Images
Society members are aiming to image the Sun everyday. The project started in 2011 and this web page will now be updated from the top down as new images of particular interest are produced. The daily images are uploaded to the MAS Facebook page.
Members - please submit your images to: webmaster@manastro.org.

Polar faculae are once again quite conspicuous in both hemispheres.
02/08/2017 - © K KilburnIn H-alpha I had to do a lot of cloud dodging so optimal tuning was difficult. However AR2670, with its fringes of plage sits in a complex bipolar magnetic region that is clearly footed in the southern hemisphere but which has north-reaching extensions, possibly as far as the equator.

02/08/2017 - © K KilburnA short dark filament is visible in the SW quadrant in a BMR that otherwise currently shows no activity in white light. A shorter filament is approaching the SW limb at high latitude.
A small prominence is visible on the SE limb and there was a bigger, much fainter cloud on the SW limb, near the filament, but this is hardly visible in this processed image.
