Description
C/2014 Q2 (Lovejoy) was observed around perihelion (2015 January 30) on
15 nights between 2015 January 21 and February 11 using the TADer 0.3-m
astrograph telescope at Teide Observatory (IAC, Tenerife, Spain). Two
large spiral jet structures were observed over several cometary
rotations. A new method of searching for periodicities in the PA of
spiral jets in the coma region at a fixed distance (20,624 km) from the
cometary optocenter is presented and used to determine a nuclear
rotation period of 17.89 ± 0.17 hr.

Minor Bodies of the Solar System
This project studies the physical and compositional properties of the so-called minor bodies of the Solar System, that includes asteroids, icy objects, and comets. Of special interest are the trans-neptunian objects (TNOs), including those considered the most distant objects detected so far (Extreme-TNOs or ETNOs); the comets and the comet-asteroid
