Thanks Philip, It’s taken 6 years to get a weather break for the QUA’s here too! The HD video cams have produced some exceptional results this year! I’m slowly becoming intimately aware of all little bumps and wrinkles of each shower. The Quadrantids really do have a strong Mg signature, even in the near UV the broad feature is an unresovled Mg triplet.
Whilst reviewing my Narrow Field of View Experiment I noted that most of the QUA’s seemed to have a very uniform light profile, both radially and axially. I’ve put a video on YouTube showing this. https://youtu.be/c8HP1V-5Eik
