[Aavso-photometry] what happened to these stars?

[Wolfgang Renz]

Hello Yenal 

These are galaxies not stars.

For diffuse objects, its always good to check at:
NED - Search for Objects Near Position
http://nedwww.ipac.caltech.edu/index.html
http://nedwww.ipac.caltech.edu/forms/nearposn.html
It finds:
Object     EquJ2000.0               Type
NGC 4666   12h45m08.6s -00d27m43s   G  
NGC 4668   12h45m32.1s -00d32m05s   G
for your two objects.

Clear skies
 Wolfgang
