[vsnet-chat 5089] eta Carinae

Hi Bish and others,
 
Harry did another measure of eta Carinae on 2 February. Here are the preliminary results for this and the first measure:
 
 
JDH -2400000       V         B-V       U-B
52302.8814        5.144    0.722    -0.316
52307.9694        5.159    0.697    -0.327
 
Differences        0.015    0.025     0.011
 
We did this mainly to confirm that there was nothing too much wrong with the first measure. It seems from these that Harry is still getting +/- 2% photometry on this object. We'll do a calibration run later in the season to confirm that there hasn't been too much drift in the transformation coefficients since year 2000.
 
Regards to all,
Stan
