At times there are many sunspots while at other times there\u00a0may be none.<\/p>\n<p>A telescope will also show you apparent &#8220;surface&#8221; of the Sun with its granulation giving it a mottled look. The disk of the Sun can also been seen to not be as bright all over, the edge being very slightly darker than the middle. Near the edge of the solar disk bright patches of light called &#8220;faculae&#8221; are sometimes seen.<\/p>\n<p>There&#8217;s a lot to look out for.<\/p>\n<p>If you feel you want to do a bit more, you can also try counting the sunspots on a daily basis using one of our <a href=\"\/documents\/solar\/SPA-Active-Region-and-Relative-Sunspot-Monthly-Activity-Form_2.xls\">monthly counting forms<\/a> (this is in MS Excel) and sending your results in to the Solar Section by email at the end of each month. This is one of the ways we monitor solar activity in the SPA. Another project is to try drawing sunspots and other solar features.<\/p>\n<p>More advanced is the viewing of solar &#8220;prominences&#8221;. These are seen at the edge of the solar disk using a Hydrogen-alpha filter. These filters (often combined now with a purpose-made small portable telescope) will show features on the solar disk called &#8220;filaments&#8221; and &#8220;plages&#8221;. Occasionally bright solar flares may be seen too if you are looking at just the right moment.<\/p>\n<p>Taking images of the Sun a daily basis is a highly rewarding experience provided you stick to the safe methods explained in our observing guide.<\/p>\n<p>The Sun can also be imaged in Hydrogen-alpha and in Calcium light (CaK) using purposely manufactured filters and scopes. This is more difficult to do but is worth the effort.<\/p>\n<p>Solar eclipses are rare but can be seen if you are in the right geographical location at the right time.

Never make your own solar filters from household items. Never look at the Sun with the naked eye even when it is low in the sky or covered by mist or fog. Never take unnecessary risks while solar observing.\u00a0<\/span><\/p>\n<figure id=\"attachment_1839\" aria-describedby=\"caption-attachment-1839\" style=\"width: 300px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1839\" src=\"https:\/\/www.popastro.com\/solar\/wp-content\/uploads\/sites\/11\/2018\/01\/hand-and-ipod-in-hand.jpg\" alt=\"Snapping Sun with an iPod\" width=\"300\" height=\"200\" \/><figcaption id=\"caption-attachment-1839\" class=\"wp-caption-text\">Using an iPod to take a picture of the Sun through a telescope with a full aperture solar filter fitted.
