Solar observations: September 2018

Each day, weather permitting, Monty Leventhal observes the Sun, our closest star, and records activity such as solar prominences, sun spots, coronal mass ejections (CMEs) and solar flares. Monty reports his findings at our monthly meetings and for some time now it has been obvious that we are in a period of very little activity on the Sun. HIs observations are collected by a number of organisations around the globe and contribute to research. Here is a summary of Monty's September 2018 report:

For the month of September 2018 all activity once again on the Sun remained extremely low. A total of 18 Observations were made for the month with the remaining 12 days being cloud covered and/or rain. A total of only 2 groups were observed. This included one group in the north and one in the south, comprising of 2 spots in the north and 3 spots in the south giving a total of 5 Sunspots. This is the lowest Sunspot count since 2011 with the exception of January 2018 when there was only 4 Sunspots in 2 groups.

The average Relevant Sunspot number for the month was 3 and the average CV was 1.3

Most Prominence's observed once again were quiet faint.

No CME's or Flares were observed.
