Home > Alert Notice 523: Correction to AAVSO Alert Notice 522

July 1, 2015:  In AAVSO Alert Notice 522 [1]on the upcoming observations of the black hole X-ray binary V404 Cyg by HST, the date of the detection by the Swift satellite was incorrectly given as 2015 June 16.77197 UT (Barthelmy et al., GCN Circular 17929 [2]). 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 [3], which announced the outburst.

Thanks to Patrick Schmeer for drawing our attention to this error.

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