As T CrB is 2,630 light-years from Earth, light from the binary system requires 2,630 years to arrive at Earth. The nova we will see occurred over 2,000 years ago, but its light will reach us next month. 

T CrB is one of ten recurrent novas recorded that erupt on time scales of less than a century. On average, T CrB undergoes a nova process once every 80 years.
