UPCOMING METEOR SHOWERS: SEPTEMBER 2014

Even if no big meteor showers hit the Earth in September, this month deserves lot of interest by MS enthusiasts. Sporadic meteors flux is at its annual maximum in this period, thus providing relatively good rates especially during morning hours.
Among showers, Aurigids (peaking September 1st) is expected to reach moderate ZHR (6 hr-1). This shower has produced short outbursts (with EZHR up to 40 hr-1) in 1935, 1986 and 1994, and a remarkable outburst (EZHR= 130 hr-1) in 2007 with many bright meteors followed by a tail of fainter meteors. Anyway, a strong display of Aurigids is not expected this year.
Even September ε-Perseids, after outstanding, unexpected ouburst of Sept. 9th 2008, should not provide strong rates in 2014, but its worth checking!
Daylight Sextantids should provide good meteor rates around the end of the month. Their maximum is expected on September 27th around 17h UT this year, but observations in previous years indicate that the peak date may vary considerably: maximum may fall between Septemeber 26th and 30th. In 1999 for example, a strong return was detected at λsol = 186, equivalent to 2014 September 29th, while in 2002, the September 27th peak was not found, but another peak was detected around Sept. 29-30. It seems plausible that several minor radio maxima detected in early October may also be due to Sextantids.



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

Aurigids
Active: August 28 September 05
Maximum: September 01 (λsol= 1586)
ZHR: Low (6 hr-1)

September ε-Perseids
Active: September 05 September 21
Maximum: September 09 (λsol= 1667)
ZHR: Low (5 hr-1)

Sextantids (Daytime shower)
Active: September 09 - October 09
Maximum: September 27 (λsol= 1843)
ZHR: Medium

2014 Perseids Overview

2014 Perseids reached the maximum in the first hours of August 13th, thus fitting well the predictions. But ZHR at peak has been below the expectations, reaching only about 70 hr-1, which is one of the worst values seen in recent years. Although this value has been calculated using data derived by visual work, and in 2014 full moon light might have biased the observations, the general feeling is that even radio-Perseids were not at their best in 2014. See Perseids visual activity profile on IMO website .
