That is really cool. Congrats.
I saw the article in September S&T page 49 showing a similar plot.
I would think Paul Maley who set up in Florence, AZ would suggest to the source
of your image that they stop using circular to oval rings to denote an
asteroids shape. I highly doubt his data was visual, but rather digital and as
such is accurate to say the asteroid is not round given all the other data
points.
Besides, round to oval is a level attained by Planets by passing rule; (b) has
sufficient mass for its self-gravity to overcome rigid body forces so that it
assumes a hydrostatic equilibrium (nearly round) shape.
S&T did not use the oval, fortunately, as the other asteroids in the article
are anything but round....
I always like reading the asteroid articles. Good job!
Steven

Subject: [sac-forum] Asteroid Thyra using occultation timings
Paul Lind posted on AZ-Observing earlier today this:
Congratulations to SAC members Mike Collins and Wayne Thomas for their
participation in mapping the shape of Asteroid Thyra using >occultation
timings. They were among the eleven timers whose data is featured in a plot
in September S&T, p 49. Another name on the list >is Tony George of
Scottsdale. I'm not sure if he's a SAC member, but everyone involved should
be congratulated.
Paul
