Pretty cool Tom. What does the rotation period look like at this point?
Or will you need a longer light curve? -Dan
A lightcurve for 4078 already exists, although it is
not of the best quality, but the period is near 4.8 hours:
Tom's new results will be an additional dataset to allow
shape-modelling downstream. This requires further observations
at apparitions when the viewing geometry differs significantly
from previous ones. The orbit has inclination (about 12 degrees)
such that the viewing angle changes quite a lot, so the
lightcurve morphology should be significantly different
as well. I recall that some years ago it was way south in the
constellation Telescopium, while in 2020 February it'll be
way north again near the northwest corner of Cancer.
