More Accurate Times for Spectroscopy?

I would like to ensure my observations are concurrent with your spectroscopic observations. Are these dates UT? Is is possible to provide timing in UT for each specific YSO? Or perhaps anything more specific that would assist us in providing concurrent photometric observations?

Yes these dates are UT as…

Yes these dates are UT as stated in the notice. Unfortunately we can not provide timing because at the observatory they'll observe when they can. However, observations on the same night will still be highly valuable.

 Thank you Mr. Kahar for updating the alert text and clarifying your request for observations. I now understand that observations taken after sunrise has occurred at Caro Alto will be of benefit to your study.
