I've calculated the E(B-V) for HD118978, it is 0.04 which is quite low. I think the reason it doesn't feature on François' spreadsheet is that it is luminosity class III rather than V. But B9III is in pickles so we have a reference to work from.
So all in all it looks like choice, and it seems most people are using it already
Malc,
Missed that one!
As you say - a textbook copy.....makes me feel better!
At least the equipment is working well - PHD/Lodestar, Spectra-L200/300, ATiK314L and the Neon and Filly ref lamps as well as the NEQ6 and EQMod. All the problems are operator related!
Cloud thickened as the morning progressed. No success.
Did any one else manage to obtain some spectra??
I'm away on holidays at the Central Coast. I've got my DSLR and SA100, but haven't managed to use it. It was just naked-eye visible last night - my estimate was 5.3-5.5. Fading fast.
EDIT: oops, no, got my comp star wrong. More like 5.0+. Still fading, though.
No luck here.
On the rare occasion that the weather has cooperated, work has managed to get in the way.
At least it is giving me time to read through all of the interesting things posted here.
I also have cloud. Clear days and cloudy nights.
It should clear up tomorrow or Saturday so I should be able to get another spectra then work permitting.
Very frustrating!!
I'm reviewing the possible effects of the spectral flats on the continuum....and finalising my notes on the necessary focusing accuracy for the telescope and the collimator/imaging lens in a slit spectroscope.

And working on submitting your spectra to ARAS of course
Amazingly it is still too hot tonight to try to use my cameras. It is 32deg at 10pm. This is 15deg hotter than usual. I wouldn't be able to cool them enough even with water cooling. Also the water container in my observatory is probably sitting at 30deg as well so not much use really. I will have to hope it is better tomorrow.

its 24 here at the moment , very humid and the sky is murky, with clear patches. i was hoping to get something this morning
Still 24 here and very humid, so much so we have a fog? Imaging is out however I can see it without binos slight averted vision. Looks a tad dimmer than a few nights ago looking at the sc I would say between 4.7 and 5 ish
Well it's a dry southerly. Can seethe pointers and crux clearly as too the nova. Amazing as twilight is well underway to sunrise. Hope someone did well. There is a slight colour to it when compared to hadar and crux. Wished I setup to image it now, oh well?
. I will have to hope it is better tomorrow.
