It will pass approx 5 lunar distances from Earth March 21 and be visible in larger scopes for a couple of nights.

Using Starry Night, I have plotted its path during the Australian Night times of March 20-21 and March 21-22.
On March 20/21, it moves on average at 1 degree per hour (twice the speed of the Moon against fixed stars) between 11pm and 5am local time.
It reaches a maximum brightness of mag 11.6.
On March 21/22, it doesn't rise until about 2am on March 22.
From 2am to dawn, it moves on average at 2.5 degree per hour (five times the speed of the Moon against fixed stars) but much fainter with the magnitude fading from 12.6-14 over 4 hrs. You can generate a custom ephemeris for your own location using the NASA Horizons or MPEPH web applications or enter the Besselian Elements below into your favourite planetarium application.
