I’m glad you mention a possible “quenching” of the V component. This was also my very first impression when I saw my first spectra. I did not have time to check the spectra I registered yesterday (27.05) to confirm this trend. Perhaps it could also be an effect of momentary pulsations which could be the precursors of the coming eclipse?
In the beginning of next week I will certainly email you my spectra. As the weather here is changing to mainly cloudy and rainy with thunderstorms I hope to register next spectra in the second half of next week as the weather will be good again. Anyway I will contribute to this project on a regular basis.
