UPCOMING METEOR SHOWERS: NOVEMBER 2014

No big showers will await MS enthusiasts this month. Anyway, most interesting shower in November remains the Leonids, although the most recent perihelion passage of its parent comet (55P / Tempel-Tuttle) is dated 1998 and this year seems unlikely to produce enhanced rates.
The “background” maximum is at nodal crossing, λsol=235°27, equivalent to 2014 November 17, 22h UT, ZHR = 15 hr-1.
Anyway, this year there may be more than one peak. Researcher Mikhail Maslov has suggested the nodal maximum could happen around 16h UT on November 17th instead (with ZHR around 10-15 hr-1), while Jeremie Vaubaillon has indicated the Earth could encounter the 1567 AD Leonid dust trail at 09h17m on November 21st (but ZHR is uncertain, maybe undetectable).

α – Monocerotids produced the last outburst in 1995 (30 minutes duration with top EZHR about 420 hr-1 for five minutes). Recent modelling by Esko Lyytinen indicates that their main dust trail will not cross Earth’s orbit again until 2017 and 2020 and only a weak AMO return may occur in November 2019. The next strong AMO outburst is predicted for year 2043.

Around the beginning of the month, pay attention to Taurids. The complex of Southern and Northern Taurids is associated with comet 2P/Encke and sometims produces an unusual activity of bright-to-fireball class meteors.



For Radio Observers, the (Theoretical) UT peaks for upcoming showers in November 2014 are as follows:

Northern Taurids
Active: October 20 – December 10
Maximum: November 12 (λsol= 230°)
ZHR: Low (5 hr-1)

Leonids
Active: November 06 – November 30
Maximum: November 17, 22h UT (λsol= 235°27)
ZHR: Medium ( 15 hr-1 )

α-Monocerotids
Active: November 15-November 25
Maximum: November 21 (λsol= 239°32)
ZHR: Variable, but typically low
