We have had poor weather in December so I haven't been able to do much observing. I did have some clear skies last night but with a full moon.
I observed GAIA DR2 4636654969717900032 which I have observed before. It is a mostly flat featureless spectrum.
I also observed the second star on the list without a name but it is UCAC3 157:43452 at mag 12.3 in CMa.
It shows some features but no emission. Both were 30 mins of exposure. More time is probably needed but since there wasn't any emission I didn't persevere.
