I haven't reduced any magnitudes on this, but here is a low resolution spectrum taken with my ST-10xme and SA200 grating right after my photometric exposures:

Hi Guys

I have had a couple of observations in V & B and looked at the B-V; using the VStar plug-in.  It has blued markedly also like it did in previous brightenings.

Hello,

thank you very much to everybody for the alert. Although yesterday clouds were present and disturbed the observation, I was able to catch this spectrum. Really impressive the P-Cygni profiles in H-beta and Fe II triplet. These bands display a gas-expansion speed of ca. 660 km/s for the H-beta band, and 600, 670 and 477 km/s for the Fe II triplet. Of course, these measures should be confirmed with a more resolution spectrum.

Greetings,

Fran
