Best times to observe asteroid Pallas (2 Pallas) between now (late 2008) and 2020

Just for fun I've been checking here to see when a number of asteroids will be closest to Earth (and thus the best times to observe them), and by coincidence the asteroid 2 Pallas is at its closest approach to Earth right now, the closest it'll be until 2014.

16 December 2008 ----- 1.562 AU
21 April 2010 ----- 1.947 AU
1 August 2011 ----- 2.549 AU
30 September 2012 ----- 1.961 AU
24 February 2014 ----- 1.232 AU
3 June 2015 ----- 2.393 AU
24 August 2016 ----- 2.401 AU
3 November 2017 ----- 1.7 AU
29 March 2019 ----- 1.582 AU
