Mont Mégantic now on board!

Hi everybody,

First, I would like to say thank you to everybody that has been taking data for the campaign (spectroscopy and photometry)! We will have a wonderful dataset

Please continue taking data, its greatly appreciated.

Noel and I are presently observing at Mont Mégantic Observatory. For those of you who don't know, it is a 1.6 m telescope in Québec province, Canada that is run jointly by the Université de Montréal and Université Laval in Québec city. Tonight, we got our first spectra for the campaign

There is an example attached to this message.

Clear skies!
Nicole (St-Louis)

Hi Nicole, very good to know that OMM no started. For curiosity: What's the exposure time and S/N? Watching down to Lac Megantic now must be sad, I guess. Reminds me how good is our live... Cheers, Thomas

Berthold -

We're just happy it cleared off for tonight. We have more time from Sunday - the 28th of the month.

Here's an ipod picture of the telescope.

Betreff des Beitrags:	Exposure times
Hi Thomas, The exposure time for the spectrum you are looking at is 2 mins! and the S/N is 200 in the continuum! and probably 300 in the stronger lines. We have 3 series of 3 spectra with 2 min-exposures each spread over a period of about 5 hours Yes, the tragedy in Lac Megantic is really sad. There will be rules that will change in the transport industry I'm sure. Cheers Only about 30 minutes left to observe PS: For the next two days we have to leave the telescope for the ''Festival d'astronomie'' an event, if you remember, for the general public who can come up and look through the big 1.6 m telescope! Nicole

Betreff des Beitrags:	big telescope
Hi Berthold, We do indeed have a bigger telescope but of course we have such a small number of nights that we could not do a project like this one without the smaller telescopes. And I am very impressed by the quality of the spectra obtained with the smaller telescopes! Nicole

Hello Nicole, hello Noel, many thanks for so fast reply and also thanks for the pictures, thus I can better fancy how are your working conditions..... nice instrument, indeed! Interesting to hear, that you need only 2 minutes for these bright spectra....great! cheers berthold

Lovely spectrum! Note that it?s NV 4601/19 (doublet, approx.), not 4804, and CIV 5802/12 (doublet too, approx.). Can you get min 2-3 spectra for each of WR134, 135, 137 spread over time on a clear night?

Lovely telescope! Good thing it?s not in Chile, otherwise we?d have trouble doing WR134, 135, 137. But for WR6 through 115, Chile would be OK...

Megantic is observing again tonight! Skies are beautifully clear, and we already got each WR star twice! (We got each three times total three nights ago, but there was more of a learning curve then). I'm hoping for 4 spectra of each tonight in Quebec. We might even get some aurora tonight...
