Lightcurve results for 1361 Leuschneria. Derived period 12.089 ± 0.0035 hours. Amplitude of 0.7 ± 0.05 magnitude.
1361 Leuschneria is a main belt asteroid with an estimated diameter of about 20 km. It was discovered on Aug 30, 1935 by E. Delporte at Uccle. The semi-major axis is 3.08 AU, the eccentricity is 0.129 and the inclination is 21.59 degrees.
This asteroid was observed on 5 nights nights during June 2015. Despite this number of nights the full lightcurve was not observed. Analysis of the data indicated a period of just over 12 hours, so it is very difficult for one location to obtain a full lightcurve.
Further observations were obtained over 12 nights between February and May, 2011. This data supported the 2004 results with the period being determined to be 2.52765 hours and the lightcurve being somewhat asymmetric.
I also attempted to observe the asteroid in 2012 for shape modelling, however on this occassion poor weather prevented me from obtaining any useful data.
