Visual?

Any value for visual observations, or is this primarily a CCD campaign?

Visual observations would be

Visual observations would be useful in setting a baseline and understanding how variable the source is in a relative sense at the time of our HST observation.

Hi all

Hi all. I am Mark Reynolds, the PI of this HST study. 

These observations will play a crucial role in allowing us to constrain the disk/stellar emission in the optical and help us to dis-entangle the various components that will contribute to the UV spectrum that HST will obtain.

If there are any questions, please feel free to ask!

Finally, many thanks to Elizabeth for setting this up.

HST Schedule

Many thanks to those who have observed this target so far!

I have recieved the HST schedule and the UV spectroscopic observation will occur on 07 Oct 00:23:57 UT (approx. 20:30 EST on the 6th).
