Greetings,

 

Did a search on the forums but did not find a link as of yet so I thought I would post.

Hope this is in the right forum. :-)

 

"NASA’s New Horizons mission is seeking public participation in a project aimed at imaging the two closest stars, Proxima Centauri and Wolf 359, from Earth on April 22 and 23, the same day the spacecraft will photograph them from almost five billion miles (eight billion km) away."

I did not see contact information as of yet.

 

Observation Dates and Times

These times specify when to observe the two stars and obtain images simultaneously with the New Horizons spacecraft. Any observation obtained within a week of these times, however, will still provide a valid demonstration of the Earth-New Horizons parallaxes.

 

 

 

Wolf 359                                  
April 23, 2020 04:00 UT         
April 23, 2020 10:00 UT          

 

 

Proxima Centauri

April 22, 2020 13:00 UT

April 23, 2020 05:00 UT

I cannot image Proxima Centauri it can only be viewed south of latitude 27°, too far south for me.

 

Wolf 359 - Stellarium lists this as a "custom object". Is this correct?

Edit: I see Wolf 359 is the same object based upon the RA-Dec coordinates on NASA website.
 

Why does Proxima Centauri have 7 different names? Is this useful or confusing?

Every astronomical catalog created assigns its own designation to an included object.  These catalogs contain different sets of measured/inferred quantities for the included objects.  Cross-referencing them aids looking up different quantities.
 

Basic information, like coordinates, are epoch dependent, so a more recent catalog like Hipparcos would have more current coordinates than, say Henry Draper.

Only seven? Surely there are more than that. Useful, confusing, or whatever -- multiple designations are the name of the game in astronomy.

They're also the bane of my observations list!

Seems like a cool event, too bad I can't see proxima from my latitude :(
