Hi

Attached are a variety of solar wavelengths imaged on the morning of the 3rd Feb LT.

I have included Ha, Na(D2), Hb and CaH images together with the spectral analysis of the data compared to reference distributions. This excellent information is one of the features of Doug Smith's free solar reconstruction software.

Reconstructed frame numbers are:
Ha 11 frames
Na(D2) 6 frames
Hb 4 frames, and
CaH 8 frames.

I have also attached a single capture frame in CaH and one showing both Na D1 & D2 lines, at about half way through capture showing what appears on the screen in the raw data. The horizontal direction is spatial (across the sun) and the vertical direction is wavelength.

All data were taken through my 100mm f/9 refractor with home made spectroheliograph attached..

Cheers
Maurice
