Call for Observations: Meteors from comet C/2015 D4 (Borisov)

Published 2017 July 15
Southern African observers have a unique opportunity to confirm the existence of the potential meteor stream from comet C/2015 D4 (Borisov) on the early morning of 2017 July 29. The earth passes very close to the predicted centre of the 1-revolution stream at 02h22 SAST, at which time southern Africa is favourably placed to observe potential meteors from the comet’s debris stream. The next opportunity with earth so close to the centre of the stream only occurs in 2029, when southern Africa is also favoured, but the comet is then a further twelve years past perihelion. Observations are requested this year to confirm any meteors from the parent comet which passed perihelion in its 700 year orbit most recently in 2014. Read more.

ASSA Symposium 2018 website

The 11th ASSA Symposium will be held in Cape Town from Thursday, March 08 to Sunday, March 11, 2018.

The theme – Amateur Astronomy in the Digital Data Age – has been chosen to promote the link between professional and amateur astronomers. The advance of astronomical technology with large surveys has opened new avenues where the amateur community can contribute to science: variable and double star work, comet discovery, supernova discovery, etc.

The four-day event starts with a “History of Astronomy in Southern Africa” session on Thursday, March 08. The “Astronomy in the Data Age” session starts on Friday, March 09. The symposium dinner is on Saturday, March 10.

Visit the ASSA Symposium 2018 website for further details. Past symposia are documented in the Historical Section’s symposia archive.
