V1454 Cyg outburst

Hi all,

Has someone been able to follow the outburst of V1454 Cyg? I wonder if it's a superoutburst?

Regards,

Eddy

a glimpse tonite

I barely managed to take a few V-filtered frames before clouds blocked it. I'm not sure I can get good photometry out of it (after getting some sleep), but just by looking at a few stacked frames I'd say it's between 14.7 and 15 now.

See for yourself:

I've never observed this star before, but I'm getting a set of B & V images to average now, and will report back after analysis.

I averaged 3 x 120 sec in V and 3x 240 sec in B in VPhot and found it at V = 14.934 and B =15.210 with 4 comps (not transformed) on 9-17-2017 at 02:42:54 (JD = 2458013.61313)  SNR only 38 in B and 54 in V, so longer exposures would be helpful for another try (17" f/6.8 telescope).

Have not reported this, as VPhot was being funky and would not allow me to designate a check star, which I need for both the AAVSO report and to report transformed measures.  Will try VPhot again in the morning, and see if I can report transformed mag's.

Clear skies,

15ish indeed

FWIW, I submitted a singe datapoint from my cloud-interrupted session last night, V=14.996 untransformed, +/- 0.05 as a conservative error estim.

I'm new to this type of variables, so please excuse my ignorance and correct me if I'm wrong: from present data it looks like this is a normal outburst and not a super-outburst, and one would expect this kind of event to last for perhaps a week or so?

EDIT: actually I'm confused after reading some more on  this ...can someone clarify what would make it a superoutburst? The very short period vraiations reported here would be the superhumps of a superoutburst?

Data Added

I was able to create the AAVSO report this AM, and have uploaded the data.  I know nothing about this star, just wanted to help with a little data for those who do.  I'll attempt to attach the report here.

Having transformed the measures, the values are a bit dimmer -- 15.002 in V and 15.174 in B.

Clear skies,

 

Brad
