GCN 23740, 23747) had errors in AB corrections, and hence the AB\nmagnitudes were reported to be a bit fainter than real. The Vega magnitudes\nare correct. Also, the reported UT time in the table and the text of Im et\nal. (GCN 23747, 23756) had errors. Below is a summary of our reported\nphotometry with corrections to the AB mag.\n\nFilter Date UT-start Vega_Mag (AB mag)\nK   2019-01-16 05:06:05.011    15.5 +/- 0.1   (17.4 AB)\nH   2019-01-16 05:26:45.974    16.5 +/- 0.1   (17.9 AB)\nJ    2019-01-16 05:47:58.042   17.5 +/- 0.1    (18.4 AB)\nJ    2019-01-17 05:31:27.984   18.0 +/- 0.1    (18.9 AB)\nJ    2019-01-18 08:30:12.989   18.3 +- 0.12    (19.2 AB)\n\nWe apologize for any confusion that this might have caused."
