[vsnet-alert 24269] Re: LMC V1341: new recurrent nova eruption!

[Berto Monard astroberto13m@gmail.com via vsnet-alert]

Observations of V1341 in the LMC were done at CBA Kleinkaroo on 11 May
2020, five days after the initial detection of the outburst.

Unfiltered timeseries observations over a 0.08d period showed the object at
a mean magnitude of 15.86CR. The LC shows an apparent brightening during
that period, which in view of the colours of nova and comparison star,
might be genuine.

Filtered photometry before and after the TS run:
2020 May 11.71 :  16.10V, 15.96Rc, 15.78Ic
2020 May 11.79 :  16.22V, 15.99Rc, 15.58Ic
These magnitudes have uncertainties of more than 0.2 and are also affected
by increasing airmass. Hence the apparent but exaggerated fast reddening of
the nova during that period.
