Correction to AAVSO Alert Notice 522

on the upcoming observations of the black hole X-raybinary V404 Cyg by HST, the date of the detection by the Swift satellite wasincorrectly given as 2015 June 16.77197 UT (Barthelmy et al., GCN Circular17929, http://gcn.gsfc.nasa.gov/gcn3/17929.gcn3).The correct date is 2015 June 15.77197 UT.

Our sincere apologies for this error!

The date was correctly given in AAVSO Alert Notice 520 (http://www.aavso.org/aavso-alert-notice-520),which announced the outburst.

Thanks to Patrick Schmeer for drawing our attention tothis error.

Coordinates for V404 Cyg: 20 24 03.83 +33 52 02.2  (J2000.0)
