Fe II line evolution in 13 days of Nova Sco 2024

[2SPOT]

Our Nova spectrum of today (#16), It becomes weaker and weaker at mag. V=10.5 according to AAVSO photometric data, so our spectra are increasingly noisy in the blue, but we'll still be able to make a few spectra over the next few nights.

And the H Alpha line (order #34)

[2SPOT]

our spectra #17 and #18 of this Nova.

The evolution in 48 hours is no longer significant.
Now, we'll produce just one spectrum every 3 days, as long as the magnitude allows us to follow the nova with the eshel spectrograph.



And evolution on order #34 on H Alpha in the last 48h.

Hi Guys,

Just a quick submission for PNVJ17261813-3809354.

This is from the Watson 24" PlaneWave at Obstech, La Sauce, Chile using the remote automated FlexSpec1 spectrograph at R=1750.

This instrument is still in its commissioning phase but given the interest in this object I thought these observations might be of interest.

Your comments would be very useful.

We can still easily 'see' this object and can still obtain spectra. Should we continue?

Kind Regards

Tony

Hi,

Most recent observation attached. I should have stated originally that we're able to calibrate to 9122A.

Good structure and changes in the NIR.

Regards
The FS1 Team.
