Some morning Sun on the 10th Feb

Hi all

Some SHG morning sun Ha images attached & via link below.

I've also attached a dopplergram from one scan taken at 2310UT.

This was generated by creating two different images from the same scan by shifting the wavelength used by 0.4A either side of the Ha line.

In the image the red shifted data is moving away from us (but is shown as being blue in colour), and the blue shifted data (shown in red) is moving towards us.

I've also attached a negative version of the Ha image.
