Observing the supernova in NGC 5128! After reading the article about the school finding the supernova in NGC 5128 (Centaurus A) we requested to observe the supernova in order to see if it was still visible. Our image was taken on the 21st of March 2016 at 19:44 UT with a 1m telescope at Las Cumbres Observatory Global Telescope Network, Sutherland node. In addition to this, we used a Bessel-R filter and an exposure time of 150.0s. The right ascension and declination of this lenticular galaxy in which the supernova is located are 13:25:27.6 and -43:01:08.96 respectively.!

We then downloaded the image from the Las Cumbres Observatory Global Telescope Network website (lcogt.net) and using the Starlink GAIA software we were able to edit the image in order to make the supernova more pronounced. Firstly, we flipped the image to match the orientation of our reference image. We then adjusted the Auto-Cut feature in order to make a contrast between the supernova and the other contents of the galaxy, especially the nearby bright star. Upon a clear image being formed, we decided it wasn't necessary to change the Colour Map or Intensity Map filters. Finally, we took a screenshot of both the whole galaxy and a closeup of the supernova.!

Close Comets! We also attempted to observe two comets named 252P and P/2016 BA14 which made extremely close passings by Earth (the 3rd and 5th in recorded history). Unfortunately we were unable to get any images from the Las Cumbres Observatory Global Telescope Network due to adverse weather conditions. Comet 252P came within 0.036 AU of Earth between the 20th and 22nd of March and P/2016 BA14 came within 0.024 AU of Earth between the 22nd and 23rd of March. AU stands for `Astronomical Units', where one AU is equal to the distance between the Earth and the Sun.
