Not knowing refraction and hence main correction I will ignore it and leave it as an exercise for the reader to do that correction to my answers. ( normal refraction is likely quite different for my two answers )
Change of dec is .7 min/hr or .002moa/sec.
By slope analysis (see my last post for explanation of that process)
the MT time is 6hr 39min 32secs if observer is north of sun and 6 hr 40min 23secs if observer is south of sun
Hs of 7d 9.4m -> co Ho = 82d 50.6min Sun Dec of 16d 16.6m N
@ 6hr GHA of sun = 268d 34m
We are either 82d 50.6m N of Sun = 99d 7.2m ie 80d52.8m N Lat and Longitude is
268d 34m + 9d 53m + 180d = 98d 27m W
I&C 39m32s
If S of sun Lat = (82d 50.6m - 16d 16.6m) S Lat = 66d 34m South Lat and Longitude
268d 34m + 10d 5.8m = 278d 39.4m or 81d 20.6m E
