A new Polaris is about to erupt in the sky

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.
