There is no need to wait for that comet really - any comet at similar distance from us and the Sun, at similar temperature would do to test this thermal hypthesis.
Even calculation/simulation would be sufficient for the good indicative answer...

Would Thermal radiation give off radio signals in the 21cm band for just 70 seconds then not be heard of again?
