UPCOMING METEOR SHOWERS: SEPTEMBER 2017
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.
At the beginning of the month, have a look to Aurigids, which have produced brief unexpected outbursts with EZHR about 30-40 hr-1 in 1935, 1986 and 1994. First predicted outburst happened in 2007: EZHR reached about 130 hr-1 with lot of bright meteors and a tail, in which more faint meteors continued for about one hour after the peak. For 2017, there are no predictions for enhanced rates from this shower.
Pay attention to September ε-Perseids: they produced an unexpected ouburst of bright meteors on Sept. 9th 2008 (λsol =166.894-166.921 degs, equivalent to 2017 September 9, about 16h UT) and another sharp bright meteor event in 2013 (λsol =167.188 degs, equivalent to 2016 September 9, about 23h UT). Anyway, no outbursts are predicted for 2017.
Daylight Sextantids should provide fairly good meteor rates around the end of the month. Their maximum is expected on September 27th this year, but please note that the date and timing of Sextantids maximum is actually uncertain. Recent radio data have indicated that the maximum may occur even a day earlier than expected, and 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 2017 are as follows:
Active: August 28 - September 05
Maximum: September 01, 02h UT (λsol= 158.6 degs)
ZHR: Low (6 hr-1)
Active: September 05 - September 21
Maximum: September 09 (λsol= 166.7 degs)
ZHR: Low (5 hr-1)
Sextantids (daytime shower)
Active: September 09 - October 09
Maximum: September 27 (λsol= 184.3 degs)
