In our previous report (ATEL #13687) on Insight-HXMT detection of a bright short x-ray counterpart of the Fast Radio Burst from SGR 1935+2154, we mistakenly stated that "This time delay is roughly consistent with the dispersion between x-ray and radio (as pointed out in Atel #13686), but nevertheless by about 4-5 seconds more, suggesting a possible intrinsic delay of the radio bursts with respect to the X-ray burst." We now confirm that the 8.5 seconds delay of the radio burst with respect to the X-ray burst is in perfect agreement with the dispersed delay and there is no evidence for any intrinsic delay of the radio bursts with respect to the X-ray burst.
