Great to hear you're back on the job Terry, even if it's going to be intermittent!
I've been getting an odd low-res spectrum and have attached one from last night (3 Jan 2014). No graph, I realise now that it's pushing jpeg data into places it shouldn't go! I notice a few lines that seem to be firming up but am having difficulty identifying some of them. Calibration isn't perfect but I think there's a Ca I line at 612nm and possibly an Fe VII line at 572nm. There's a line at around 628nm and even with calibration issues I can't see how it would be O I at 630nm. There's also a line at around 530nm and Fe I emissions at 527/533nm seem way too far off. Advice, opinions welcome.
Cheers -
