As of September 7th it was on the way down, at about magnitude 4.8.
Chi (χ) Cygni is plain to see in the neck of Cygnus, the Swan, not far from Albireo, Beta (β) Cygni. It's near 4.0-magnitude Eta (η), which is 2½° farther down the neck away from Albireo. Eta is orange; Chi is a deeper orange-red. See the comparison-star chart in our earlier article on this star, or in the August Sky & Telescope, page 67.

From the AAVSO site you can also get a wide-field comparison-star chart for estimating Chi Cygni's magnitude when it's at its very brightest.
