For an early astronomical treat to usher in the New Year, seek out the natural pyrotechnics of the rich Quadrantid meteor shower. Peak shooting star activity occurs within a four-hour window centred on a prediction of 8am GMT on 4 January 2020 – a time that favours UK skywatchers at astronomical dawn, or North American observers around local midnight.

The December Geminid meteor shower is generally regarded as the richest and most reliable of the major annual shooting star displays. This year the predicted peak occurs between 2h and 23h UT (2am to 11pm GMT) on Saturday the 14th, but its bright and slow-moving shooting stars will have to contend with the glare of a nearby Moon just two days after full.

Could we be in for a bumper crop of Geminid meteors just before the middle of December? There’s a good chance that we will given that their parent body, the mysterious crumbly “rock comet” 3200 Phaethon, is also making a close flyby of Earth this month.

Astronomers recall discovery of Phaethon — source of Geminid meteors

12 December 2015 Astronomy Now

The beautiful Geminid meteor shower is due to light up the heavens this weekend, but the source of the enigmatic cosmic display had eluded stargazers for more than 120 years. Then, in 1983, two University of Leicester astronomers — Dr. Simon Green and Dr. John Davies — used data from the IRAS satellite to discover 3200 Phaethon, an asteroid with a very unusual orbit.
