I looked into the circumstances of Eros' apparition and selected three times at
which simultaneous photographs of Eros may be attempted. This selection was done
by looking at images of earth as seen from Eros:

http://www.transitofvenus.nl/images/Jan31_23UT-small.png

(In the images, the night side of earth has been left light for clarity, whereas
the day side has been made darker)
Every time, at least two widely separated populated areas had to be in view as
to create suitable baselines for the parallax measurements. The selected times
are:

Jan 30 - Feb 1, 07:00 UT: North and South America
Jan 30 - Feb 1, 18:00 UT: India (Asia actually) and Australia
Jan 30 - Feb 1, 23:00 UT: Europe, India, Africa

Comments on the selected dates is very welcome!

January 1 there will be a call for participation on
http://www.transitofvenus.nl, and (hopefully) also a main page with background
information and instructions for photographing Eros and submitting your
observations.
