[vsnet-alert 15771] Re: [cvnet-outburst] Re: PNV J19150199+0719471

[Josch Hambsch]

Hi,

I have been observing this transient as well. Magnitude measurements are 
based on the new sequence available at the AAVSO. V mag = 10.64 and I mag = 
10.71.
JD around 2456444.92223d

Data are submitted to the AAVSO.

Regards,
Groeten,
Grüße,

Josch
