2004

January
The second run for more data on Tau Boo is carefully planned while the equipment is brought out of mothballs and tested.

March-April
The telescope system is once again transported to Arizona and setup at the Winer Observatory. Two runs, each two weeks long, accumulates 600 additional measurements on the star.

Summer
The null lenses are fabricated for the final figure of the primary mirror. The interferometer is completely rebuilt with automated controls and mounts for the new lenses.

Fall
Data reduction on the complete data set from 2000 and 2004 causes problems with 'aliasing' because of the long time span between data. Multiple approaches are tried to get by the problem.

Winter
A deal is signed with Tenagra Observatories for time on their 32" automated scope. A new interface system is designed and build for the Tenagra II.
