Dear Elena,
You submitted HOPR 92018 for HST program 16316 on June 14, 2021.
After review, the Telescope Time Review Board (TTRB) approves your request and awards one orbit to repeat Visit 59, which suffered a failed guide-star acquisition, leading to empty images.
The request is within the 90-day limit and the program is less than 90% complete. The failed data will be made public immediately. 
Claus Leitherer, head of the Science Policies Group, has concurred in our recommendation.
Please work with your PC to prepare a revised Phase II file. 
With best regards,
Andy
for the TTRB
