Those data are for two different stars. The northernmost one at 20:21:01.08 [305.25449d] +21:31:03 [21.51750d] is Henden USNO data and should be very good. The one closer to the nova at 20:23:08.99 [305.78745d] +20:51:51.1 [20.86419d] is Tycho data and should be pretty good also. Pick one and be confident in your result.
