The symbiotic nova AG Peg had undergone an outburst un june, 2015, the first symbiotic outburst observed.
The new ouburst began on october, 8th
This last spectrum in the data base was acquired just at the begining of the new event.
Spectra of this new event are welcome
(It could be either a new symbiotic event, or a new nova outburst)
