Analysis of the light curve for this object appears to show that it is tumbling, with rotation occurring about the non-principal axis.

The normal ?-spodumene converts to ?-spodumene at temperatures above 900 �C . Crystals are typically heavily striated parallel to the principal axis.
23.
The effect occurs whenever the axis of rotation differs slightly from the object's second principal axis; air resistance or gravity are not necessary.
24.
Czech astronomer Petr Pravec from the OndYejov Observatory believes this may be a tumbling asteroid, yet observations are not sufficient to determine a non-principal axis rotation.
25.
The latter can be done without increasing the weight of the column by distributing the material as far from the principal axis of the column's cross section as possible.
26.
These two constraints operate in different reference frames; the ellipsoidal constraint holds in the ( rotating ) principal axis frame, whereas the invariable plane constant operates in absolute space.
27.
The " feet " of the lineshape correspond to the situation when the principal axis of the coupling interaction is parallel to the magnetic field which is much less statistically relevant.
28.
The Salinas River, which geologically formed the fluvial valley and generated its human history, flows to the northwest or'up'along the principal axis and length of the valley.
29.
A number of connection axes are also planned in-between the principal axis and the sub-axis, with multi-functional service nodes to serve the whole of Lekki FTZ.
30.
It gave a well-defined rotation period of hours with an exceptionally high brightness amplitude of in magnitude ( ), and no sign of a non-principal axis rotation ( NPAR ).
