[vsnet-alert 11699] V3890 Sgr recent behaviour

[Berto Monard]

Hello,

It might be nothing unusual but V3890 Sgr is getting quite bright lately as 
shown below.
Something similar happened to V1017 Sgr two years ago with the brightness 
peak also occuring while behind the sun. Both are symbiotic stars which have 
shown recurrent nova outbursts.

Can someone still follow up on V3890 Sgr and see what happens further. For 
me the season is over.

PS I can provide the photometric sequence that I have been using since 2005
