08/06/2019 – Ephemeris – More about viewing the Perseid meteor shower: Meteor trains

August 6, 2019 Comments off

Ephemeris for Tuesday, August 6th. Today the Sun will be up for 14 hours and 27 minutes, setting at 9:02, and it will rise tomorrow at 6:35. The Moon, 1 day before first quarter, will set at 12:29 tomorrow morning.

The Perseid meteor shower has to compete this years with the bright waxing Moon, so only the brightest meteors will be visible, However even though this cuts down on the meteors visible, it happens that some of the brightest of meteors leave smokey trains, which can be seen in binoculars. Unlike aircraft contrails which are created the same altitude, meteor trains descend through the atmosphere where the winds at the different altitudes slowly bend and twist the train, tearing it up. The same occurs with any really bright meteor, Perseid or not. So remember to add binoculars to your meteor viewing kit along with a blanket, warm coat, mosquito spray and hot coffee or other beverage.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Addendum

These are screen caps from a time lapse video by Australian Phil Hart of a meteor train being torn apart by upper level winds. Credit Phil Plait’s Bad Astronomy/Phil Hart.  This was not a Perseid meteor.
