Dear All,

thanks for the great support of this HST campaign so far!

It's getting closer to the big day, and I've been in touch with STScI: they want that we communicate an update on GW Lib by

UT 13:00 on August 31st

and provide measurements taken within 24h of the COS observation, i.e. after

UT 20:33 on August 30th

Please upload any observation you make after that as soon as you can.
 

Thanks again,

Boris

This is a reminder that at least least one positive observation of GW Lib after UT Sep 12, 2017, 23:52, will be needed to get the final HST observation approved. Many thanks for your astronomical efforts!

Good observing,
