Dear Elaine,
You submitted HOPR 91893 for HST program 16430 on October 21, 2020.
After review, the Telescope Time Review Board (TTRB) approves your request and awards two orbits to repeat Visit 01, which suffered a failed guide-star acquisition, leading to empty data.
The request is within the 90-day limit and the program is less than 90% complete. 
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 and to find a suitable scheduling opportunity. The scheduling will be handled on a best-effort basis.
With best regards,
Andy
for the TTRB
