The Sextanids are active September 29 through October 9. Though, this one is more of a radio/radar shower as it occurs during the daytime with minimal activity.
The radiate is in the constellation Sextans.

The Sextanid meteor shower was first reported by Weiss (1960), who matched theoretical envelopes to the echo range-time plot from a directive radar rate equipment to find the radiant = 1558, S = 01O. The peak activity persisted from September 29 to October 3, but was noticeable only in 1957. No trace of activity due to this shower could be found in previous surveys.

Performing the numerical integrations, we also substantiated a possibility of the association between Apollo-type asteroid (3200) Phaethon and the Sextantids.
Furthermore, we roughly estimated relative maximum flux rate of Sextantids : Geminids as 1 : 3 amplitude ratio. Depending upon the flux rates and the time lags of the orbital evolution with Phaethon, we conclude that the Sextantids are at a more progressive stage of orbital evolution than the Geminids if both meteor streams are really associated with Phaethon.
