ups gem Derek, At the Journees 2005 meeting in Warsaw

I presented a poster paper about the results of the lunar occultations of
upsilon Geminorum and Antares. The
paper is attached [Link Below] In that paper my conclusion about the
position of the secondary of upsilon Geminorum relative to the primary is
0".04 +/- 0".01 in separation and 70deg +/- 20deg in PA. This
result is still preliminary in the sense that I have determined it mainly
from the comparison of your faint events with the bright events of the
others, and I have not checked Richard Nolthenius's observations fully yet,
but the result is rather consistent and it should not have large errors. You cited Richard's message: | The PA of the
secondary appears to be north and east of the primary, | in the PA=310
area is my very rough guesstimate." He wrote
"north and east", so I think his correct "guesstimate"
was PA=50deg instead of PA=310deg, then his estimate agrees well with
mine. You note that he later changed
his estimate closer to PA=0, but according to my calculations PA=0 does not
agree well with your observations. I need some more time to get my final
results using all the observations of the graze, and to clarify how all the
observations are consistent with the results, but before arriving at the
final results, it might be a good idea to show many people my preliminary results
and to get criticism from them, so I would appreciate it if you could put the
attached paper somewhere on your web site, and discuss it in public. I would also like to receive as many
observations as possible of the lunar occultations of Antares and its
companion from abroad (I used only one observation of the Antares occultation
on 2005 March 3 from the USA). Best
