Discovered in the summer of 1866 by the man more famous for finding Stephan's Quintet, Julia usually isn't an asteroid on anyone's "must-see" list, mainly because it remains fairly dim for light-polluted skies. However, seasoned amateurs in the local area have a chance with Julia from 16 to 31 August. It should be at least as bright as 9.0.

Below are the culmination times and altitudes, and Starry Night Pro Plus' magnitudes...
16 August = 2:32am / 68˚ / mag 8.5
17 August = 2:27am / 68˚ / mag 8.5 [0˚05' southeast of mag 7.4, K-class HIP 113958]
18 August = 2:22am / 69˚ / mag 8.5
19 August = 2:17am / 69˚ / mag 8.5
20 August = 2:12am / 69˚ / mag 8.5
21 August = 2:07am / 69˚ / mag 8.5
22 August = 2:03am / 69˚ / mag 8.5
23 August = 1:58am / 69˚ / mag 8.5
24 August = 1:53am / 69˚ / mag 8.5 [0˚10' south-southwest of mag 7.7, G-class HIP 113438]
25 August = 1:48am / 69˚ / mag 8.5
26 August = 1:43am / 70˚ / mag 8.5
27 August = 1:38am / 70˚ / mag 8.5
28 August = 1:33am / 70˚ / mag 8.4
29 August = 1:28am / 70˚ / mag 8.4 [0˚04' east-southeast of mag 7.3, F-class HIP 112960]
30 August = 1:23am / 70˚ / mag 8.4
31 August = 1:18am / 70˚ / mag 8.4

During the nighttime periods of 16/17 August, 23/24 August, 28/29 August and 29/30 August, Julia is so close to brighter stars that one may be able to discern its movement over two to four hours.
