Keep a look out for any white spots (Storms) that may be visible amongst the clouds.<\/p>\n<p>One notable effect that happens as opposition approaches, the rings of Saturn start to become much brighter. This <strong><em>Seeliger Effect\u00a0<\/em><\/strong>is caused by the ring particles not casting shadows on one another, due to the angle of the Sun to us on Earth viewing the planet. The brightness increase should occur a couple of weeks either side of the date of opposition.<\/p>\n<p>This is shown quite nicely by <span style=\"color: #ffffff;\"><strong>Christopher Go&#8217;s<\/strong> <\/span>images of Saturn shown below.<br \/>\n<a href=\"https:\/\/astrobob.areavoices.com\/2013\/04\/28\/saturn-and-the-seeliger-effect-seeing-is-believing\/\" target=\"_blank\" rel=\"noopener\">Click here or on the image below for more details about this effect.<\/a><\/p>\n\n<a href=\"https:\/\/astrobob.areavoices.com\/2013\/04\/28\/saturn-and-the-seeliger-effect-seeing-is-believing\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large\" src=\"https:\/\/astrobob.areavoices.com\/files\/2013\/04\/Saturn-Seeliger-Chris-Go_edited-1-1024x215.jpg\" width=\"1024\" height=\"215\" \/><\/a>\n<p>This phenomena is so pronounced at times that the brightening of the planet can even be quite obvious to the naked eye observer.<\/p>\n<p>So, while it is still at its best, get out and have a look at the glorious Lord Of The Rings.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u00a0 On the 27th of June Saturn reaches opposition, adding to the plethora of planets and asteroids currently at their best.
