Astronomers report the approach of a rare cosmic phenomenon – in the night sky will soon appear in the star T Coronae Borealis (T CrB), not inferior in its brightness Polaris. Observers will be able to see its glow in the constellation Northern Crown, without using any optical devices. This event should be tried not to miss, because the next such flare will be only in 8 decades.

T Coronae Borealis is available for observation with strong binoculars now. Its brightness is about +10 magnitude, but will increase sharply to +2 at the time of the outburst. Flares occur regularly with a period of 80 years – they have been observed twice in recorded history. The last such outburst occurred in 1946. It is expected that the next burst of luminosity lasting several days will take place from March to September this year.
