Transient in vulpecula
Posted: Fri Apr 14, 2017 5:37 am
Hello,
there is a new alert in the AAVSO page about a new transient in vulpecula: PNV J20422233+2712111
The new object brights of mag. 11 and has been discovered by two independent Japanese observers. I have tried to observe this new object in the morning (sorry, i noticed this one exactly past night, when I was closing the observatory and going to sleep) and, effectively, the new object is present.
I took a low resolution spectrum but morning surprised me, so the spectrum (2x600s) is very noisy and with few features. A gaussian filter shows only weak Balmer absortion (H-gamma and delta) and a maximun intensiti near 4000 A.
It remembers me a dwarf nova near the maximun...
Sent this spectrum to the AAVSO forum, I'm going to sleep a bit...
Greetings
Fran
