Dear colleagues,
While monitoring the outburst of UG-type stars, I found there are some
probably mis-classified stars.
They are classified into UG-type in the GCVS. But some of them can be
Mira type, or some of them seems almost constant at bright state.
* V1050 Aql : R.A. 19h51m43s.4, Decl. +10o51'15", 14.5-17.5 mag(p)
It is bright and red in the USNO-A2.0, 14.6 mag(R) and 17.5
mag(B).
It is also recorded in the infrared catalog as IRAS 19493+1043.
It is also recorded as a long periodic variable NSVS
1951432+105114, with a period of 270 days.
* HN Cyg : R.A. 19h33m39s.9, Decl. +28o56'14", 13.3-16.0 mag(p)
It is bright and red in the USNO-A2.0, 12.5 mag(R) and 15.9
mag(B).
It is also recorded in the infrared catalogs as IRAS 19316+2849
and MSX5C G063.2797+04.4706.
* V1285 Cyg : R.A. 19h44m49s.5, Decl. +35o59'35", 13.1-14.8 mag(p)
It is bright and red in the USNO-A2.0, 12.3 mag(R) and 14.2
mag(B).
It is also recorded in the infrared catalog as IRAS 19429+3552.
It looks bright in the 2MASS infrared images.
* UY Vul : R.A. 20h55m52s.8, Decl. +26o40'52", 13.0-<16 mag(p)
It is bright and red in the USNO-A2.0, 12.8 mag(R) and 16.6
mag(B).
It is also recorded in the infrared catalog as IRAS 20537+2629.
It is also recorded as a long periodic variable NSVS
2055525+264049, with a period of 626 days.
* UZ Vul : R.A. 20h56m46s.0, Decl. +23o34'36", 14-<16 mag(p)
It is bright and red in the USNO-A2.0, 15.7 mag(R) and 18.3
mag(B).
It looks bright in the 2MASS infrared images.
* KM Lac : R.A. 22h13m49s.4, Decl. +55o28'26", 14.8-<17.4 mag(p)
It is bright in the USNO-A2.0, 14.4 mag(R) and 15.1 mag(B).
It keeps almost constant around 14.5-15 mag from 2007 to 2012 in
the course of the MISAO Project survey.
* LM Cas : R.A. 23h12m59s.9, Decl. +56o51'21", 15.8-<19 mag(p)
It is bright in the USNO-A2.0, 15.3 mag(R) and 16.0 mag(B).
It keeps almost constant around 16 mag from 2007 to 2012 in
the course of the MISAO Project survey.
* V381 Lac : R.A. 22h15m58s.9, Decl. +42o22'47", 12.5-<16.2 mag(V)
(Note that it is classified as NL, not UG, in the GCVS)
It is bright and red in the USNO-A2.0, 13.9 mag(R) and 17.1
mag(B).
It is also recorded in the infrared catalog as IRAS 22138+4207.
I found the following paper on this star, which suggests it is a
Mira variable.
