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 for about 20 minutes with lot of bright meteors and a tail, in which more faint meteors continued for about one hour after the peak. For 2019, 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 2019 September 10, about 04h UT) and another sharp bright meteor event in 2013 (λsol =167.188 degs, equivalent to 2019 September 10, about 11h UT). Esko Lyytinen's modelling has suggested the next really impressive SPE return may not be before 2040, and 2019 activity should be at the usual annual level, although Mikiya Sato predicts an encounter with 1-revolution dust trail on September 10, 02h06m UT, but resulting ZHR is uncertain.

Daylight Sextantids should provide fairly good meteor rates around the end of the month. Their maximum is expected on September 28th 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 2019 are as follows:

Active: August 28 - September 05
Maximum: September 01, 14h UT (λsol= 158.6 degs)
ZHR: Low (6 hr-1)

September ε-Perseids
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 28 (λsol= 184.3 degs)
ZHR: Medium
