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 (peaking September1st) which have produced brief unexpected outbursts with EZHR about 30-50 hr-1 in 1935, 1986, 1994 and 2019. 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.

September ε-Perseids produced an unexpected ouburst of bright meteors on Sept. 9th 2008 and another sharp bright meteor event in 2013. Esko Lyytinen's modelling has suggested the next really impressive SPE return may not be before 2040, and 2023 activity should be at the usual annual level.

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 2023 are as follows:

Active: August 28 - September 05
Maximum: September 1 (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 27 (λsol= 184.3 degs)
ZHR: Medium

2023 Perseids Review

2023 Perseids reached the peak as predicted, in the early afternoon on August 13, but with relatively low ZHR, about 70 hr-1. The submaximum seen on 2021 and 2022 on August 14, was barely evident this year. Have a look to 2023 Perseids activity report on IMO Website.
