Hello Kentaro

I took the trouble to read that Noguez piece. Those two really
should have done the same with Bonilla's report.

Bonilla seems to have been a careful chap and took "certain
measures" after the first day's sightings and again after the
second day's, so as to establish some basic facts:

i) he'd carefully focussed his set-up (based on the `equatorial'
telescope) on the moving objects and not on the Sun. Then, in
the evening / night he steered that pre-focussed `equatorial'
scope to the visible planets in turn and then to the Moon. The
views so gathered told him that the objects had been at a
distance much less than any planet but only a little less than
the Moon. He then apparently checked the calibration of his
focus set-up, because he was able to refine his estimate of
about 3/4s of the Moon's distance, down to about 2/3s - i.e.
approx. 242,000 kms;

ii) he'd measured the time the objects took to cross the Sun's
face to be a minimum of 1/3 of a second and a maximum of one
second (to move 1/2 degree angular). Recall they were travelling
across the Sun in a straight line from West to East; also that
they mostly appeared to be either "perfectly circular" or
"elongated" (elliptical?) to the naked eye. Think we can
discount any elongation in the photos since those `wet-plates'
must have been exceedingly `slow', while from the distance and
angular motion you can work out they were moving at quite a pace
(in addition to being quite a size);

iii) he had also contacted the observatories at Mexico (City?)
and Puebla asking them to look towards the Sun for objects of
some kind the following day. When they reported that nothing was
visible to them at the time he _was_ observing objects, he then
had some idea of their minimum parallax.

All that information, and the fact that the objects were bright
with a bright trail (or exhaust?), both changing to dark when
seen against the Sun - which rules out reflections or optical
effects around the objects since photons do not interfere with
other photons, seems to place some strong limits on the objects'
possible identities.
