The Sun is the star that gives life to Earth by shining every single day. It is therefore important to
observe the Sun and try to understand its secrets. The goals of the section are
- · Collecting the Solar observations from all around Greece.
- · Creating an archive with the observations separated in Photospheric –
- Chromospheric – Radio and Sunspot Counts.
- · Making the "Archive" open to each person interested in the observations.
- · Generating "Observing Campaigns" with specific subject.
- · Analyzing the observations and publishing the results .
- · Participation in conferences with lectures and poster presentations.
- · Organizing workshops on "How-To" do Solar observing.
- · Cooperation with other amateur astronomers around the world and other
- associations (British Astronomical Association, Association of Lunar and Planetary
- · Publishing observing guid-lines and advice on safe Solar views.
At this time the "Archive" of the Solar Section observations totals to these numbers.
- · 1430 Drawings of the Sunspots between 1999 (January) and 2010 (December).
- · 630 Images of the Photosphere and Sunspots between 2004 (January) and 2010
- · 1137 Images of the Chromosphere (Prominences, Flares, Filaments, Active Regions)
- between 2005 (January) and 2010 (December).
- · 2535 Sunspot Measurements (Daily Sunspot Counts) between 1999 (January) and 2010
- · Also, as from November 2010, a big number of observations with Sunspot Counts are
- available (more than 1500) but these observations have not been archived yet.
Also a new web-page has been created by the coordinator of the Solar section for providing "Daily
Reports" of the Solar activity with images of the Sun, articles on Major Solar Events and links to other
Greek amateur astronomers’ personal web-pages.
This site can be accessed via the following link: www.dailysolar.weebly.com and is going to be included
in the the next version of HAAA's main web-site.
