Dear all,

I've sent measurement published in DOU 2006-E48. Precovery was made with the
great help of G. Forti and M. Tombelli:

COD 644
OBS Foglia S., Forti G., Tombelli M.
NET UCAC 2
    K04V17D  C2002 02 16.44933 09 53 22.96 +05 12 42.7          21.7 V
644
    K04V17D  C2002 02 16.45593 09 53 22.28 +05 12 46.3           21.9 V
644
    K04V17D  C2002 02 16.46212 09 53 21.68 +05 12 49.6          21.5 V
644

I really don't know who sent measurement published in today's DOU and it seems
that my observations disappear in the 2004 VD17 observations block...

Perhaps my data was difficult to measure but I've not seen any other possible
moving object around the previous data in the SkyMorph image of 2002 02 16

Later I'll try to see again that images.

Sincerely

Sergio Foglia

But I was curious what effect they would have on the
