Geminids 2019 Backscatter Data

By Trevor Clifton

Pictured below is the backscatter data for the 24 hour period covering the Geminid maximum.

Some of the gaps in the data is due to high levels of RF interference which although the meteor data is logged in a text file its not printed on the graph as it may be unreliable.

Transit of Mercury

By Richard Harvey

The transit of Mercury which occurred on the 11th November 2019, was the third Mercury transit this century, (other transits being 2006 and 2016). The next transit however, won’t occur till, 2032, so we felt it important that a group observation session should be arranged for the 2019 event.

With the Sun being only twenty degrees above the horizon at first contact, and heading lower, it was vital that we found an observation spot that offered a clear view of a low horizon towards the south. The Vineyard at Halfpenny Green seemed an ideal location, and we were lucky to be given permission to use the area outside the café.

Members started arriving around 11.30, to allow plenty of time for setting up scopes in readiness for first contact at 12.30. A fine array of telescopes adorned the grass area, with refractors, reflectors, and Schmitt-Cassegrains. Baader filters were firmly secured, and photographic equipment poised in readiness.
