I made long observing series on EE Cep using star 104 (000-BCQ-031) as comp1 and found that it varies slightly as illustrated on the graph below. I suggest not using it any more, there are other suitable comps around.

@Sebastian_Otero can you have the sequence team take a look at this?
I have just added the object to VSX. It is a DSCT with an amplitude of 0.02 mag.(TESS data).
A remark has been added to VSP so only visual observers use it.

The current observing campaign specifically requests 104 as the comp, should we change?
Using TESS data Sebastian Otero has confirmed that comp 104 varies by 0.02 mag, which make it unsuitable for precise photometry of EE Cep. For this reason I suggest 000-BCQ-029 (comp 112) and 000-BCQ-036 (comp 113).

Unfortunately, NSV 25842 (000-BCQ-029) is also a 0.02mag. variable.
Using it would be exactly the same as with the 104 comp star.
Let me check the 113!!
And this is the 113 (000-BCQ-036).
Exactly the same thing…
To complicate things, even when the two comp stars are labelled 112 and 113, they are actually only 0.01 mag. different (mean 11.24 and 11.25).
