Aprils newsletters and Star Charts

Edwin Rod

Hi everyone

Please find all the usual newsletters and star charts attached, lots to have a look at this month and the new Kepler planet is one to watch as an interesting discovery. Again here is no shortage of interesting research this month too.


Last month’s email sure feels a long time ago, and how life along with the economy has changed, NZ is moving to alert level 3 from tomorrow (28/04/2020), after 33 Days in complete lockdown, we are slightly easing restrictions. It has been a tough time and the news last night of losing one of my long time astronomy friends was hard too, It was health related and not due to Covid-19.

Take care everyone
