Hazy sun 18/07/2017 + up-date

A lot of high-altitude cirrus today.

However, a nice display of prominences, although very little on the disc. These hazy conditions probably favour the black and white image rather than the colourised version, but it may be my eyes, as I am a bit optically challenged in the reds.

As a bonus, though, the haze produced a rather nice solar halo:


The haze cleared later on, so I have added another image taken a few hours later.

The prominence at about 3 o’clock is associated with Spot 2665, and you can see how it changed in the 4 hours or so between the images.
