TITLE: GCN CIRCULAR NUMBER: 25624 SUBJECT: LIGO/Virgo S190901ap: Hobby-Eberly Telescope VIRUS observations of ZTF19abvionh [correction on the peak] DATE: 19/09/03 05:50:14 GMT FROM: Maria Jose Bustamante Rosell at UT Austin M. J. B. Rosell, Karl Gebhardt, Aaron Zimmerman, Matthew Shetrone, Chris Fryer, J.
