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...

Once again all Sunspot, Prominence and Flare activity remained extremely low as we approach the Sun's Solar minimum. I expect this could occur in the coming year.

A total of 25 observations were made for the month with the remaining days being cloud covered or rain. This consisted of 17 days when the Sun was clear of Su...

The lack of solar activity over December and months prior brings a question to the writers mind. Are we heading for another Maunder minimum, bearing in mind the extreme cold conditions in the U.S.A. at present? I think not. The next 4 years might tell. Nonetheless I observe the Sun every day and there have been a few n...

Every day I observe solar activity and publish my results globally. I also report my monthly findings at the Sydney City Skywatchers meeting on the first Monday of the month. Unfortunately very low activity on the Sun continued throughout July. On the 1st only a single Hax (7) spot could be observed in AR12664, also a...

At the 5 June Sydney City Skywatchers meeting Monty Leventhal presented his May Solar observations and I was particularly interested in his observation of X-ray class of C1. flare on 28 May. This post is about a phenomenon we can view from our planet when the solar conditions are just right . 

The reason for my cur...
