Southern Hemisphere Non-Pro Spectroscopy of Eta Car

Wed, 01/07/2015 - 22:55

I am trying to get in contact with the non-pros in the southern hemisphere who contributed spectra to the campaign on Eta Car in the second half of 2014.  There is an interesting discrepancy between the observations of the He II feature reported by that campaign and the measurements from Hubble Space Telescope data.  The ground based is reported to show no change between 2009 and 2014 while the HST/STIS data show a clear change.  The non-pro data might hold the key to understanding this difference.  

Details with work I am involved in with the HST data can be found:

or

I would like to figure out what is going on and you may be able to help.   Please contact me via email jmart5 _at_ uis.edu if you are a non-pro that participated in that campaign.
