Sept 20/21/22 Meteors

Meteor activity remains strong over the past few night. Low levels of activity continue to radiate from the Perseus/Auriga area (where the Delta Aurigids and other poorly defined radiants may be active) and the Nu Eridanid radiant which is currently located near the “shield” of Orion.

The Nu Eridanids (NUE) is a newly recognized shower which has been identified in the video data of the SonotaCo network (Japan) and the IMO Video network (Europe/US, which includes the cameras operated by myself and Bob). The cameras operated by myself and Bob are part of the IMO network.

The NUE are active from Sept 3 to 24 with a peak around the date of Sept 7. Though there has not been any published work on the visual rates of this shower, it most likely only produces a meteor or three per hour for observers at dark sites. Salvador Aguirre of Hermosillo, Mexico reports that he was able to observe 2 NUEs on the morning of Sept 17 during ~40 minutes of observing under a dark +6.2 mag sky. With a velocity of ~68 km/s the NUEs were most likely created by an unknown retrograde long-period comet.
