December 2022 News and research

 

Hi Everyone

 

It’s the Summer solstice this Thursday the 23rd and let hope for some summer weather here. Make sure to note down the date of Stardate and also the Central starparty over this summer.

A range of interesting papers out this month, and if you’re interested in exo planets you are going to have some interesting reading this month.

TPAS Summer Stardate Approaches Fast

The Summer Stardate is between 20 and 23 January 2023 at Stonehenge Aotearoa, Carterton (Wellington Anniversary Weekend).  We anticipate excellent night skies for observation. This Stardate will bring an eclectic range of subjects and activities to while the time between observations.  Full details are within the program.  Tis a grand occasion to enjoy mixing with fellow enthusiasts on a simple basis.

 

Camping onsite is available for those seeking an edgy near frontier experience.  

 

This event also provides opportunities for those interested in the night sky to explore these interests with practitioners in a supportive environment.

 

Central Star Party

The eighth Central Star Party will be held from Thursday 12th January to Tuesday 17th of January 2023 (their is no camping Tuesday night) and will be held at the Tuki Tuki Camp site in the Hawkes Bay. This is the site of many previous star parties.

Time to Name a Planet

In celebration of 100 years of the International Astronomical Union, the IAU NameExoWorld  global competition allows any country in the world to give a popular name to a selected exoplanet and its host star. New Zealand has been assigned the planet HD 137388b and its host star HD 137388 and we need your help in choosing names!  You can make a submission here between 1 September 2019 and 30 September 2019 (5:00 p.m. NZST). A panel of judges will select the name of the star and the planet by 30 October 2019 and will make its submission to the IAU by the 31 October 2019. IAU will make it’s final announcement in by 31 December 2019 . The winner will then be notified via email. Please note that entries can only be accepted from people living in NZ during the time of the submission.
