09/11/2020 – Ephemeris – A virtual star party tonight

September 11, 2020 Comments off

This is Ephemeris for Friday, September 11th. Today the Sun will be up for 12 hours and 42 minutes, setting at 7:59, and it will rise tomorrow at 7:18. The Moon, 1 day past last quarter, will rise at 1:19 tomorrow morning.

The Grand Traverse Astronomical Society will host a virtual star party at 9 pm tonight. It is via the Zoom app for the smart phone, tablet or computer at zoom (dot) us. Instructions and a link can be found on the society’s website gtastro.org. It will be hosted by Dr. Jerry Dobek, astronomy professor at Northwestern Michigan College. During a virtual star party the images are produced real time or near real time using a telescope mounted CCD camera. That is if it’s clear. Images of dimmer objects like star clusters or nebulae, what we call DSOs or deep sky objects may take exposures of several seconds or minutes to build up an image. But have the advantage of being in color. If cloudy we’ll have a virtual, virtual star party.

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