Spectra of Nova Cen 2013

[hukadarn]

In Brazil the amateur astronomer Rogério Marcon (Solar Observatory Bernard Lyot, Campinas, SP), using your homemade Littrow Spectrograph, obtained a high resolution spectra of H-alpha region:

Do you have a date and time for this spectrum?    (your tinyurl link does not work)

Rob Kaufman has just posted a low resolution spectrum where the emission seems to have disappeared last night.

This seems  strange  so a confirming higher resolution spectrum could be interesting

Robin et al,

The Nova was recorded tonight at 12A/pixel. P Cygni visible in Ha....

(What's the absorption at approx. 4275A?)

[Merlin66]

Got more spectra this morning....the P Cygni profile has disappeared to leave Ha & Hb emission lines truncated in the blue....

12A/pixel, 30s exposures with the Baader grating/ Genesis

Rogério has let me know that his spectrum above was taken Dec 5th 2013 07:30 UT.

No excuse for the delays....
This is the Lo-res spectra I recorded earlier....
Shows the dramatic increase in the Hydrogen emission and the FeII....

Merlin 66,

Excellent spectra I take my hat off to all who have posted.

Good work.

Regards,

Jack

Thanks Jack!

The weather here at the moment is almost as bad as the UK (or Belgium!!)

Next clear night is "promised" for Boxing Day....hope they're correct.
