We leave it up to parents\/guardians to assess whether the person under their care is capable of the above tasks. We will also have our Sunspotter telescope at the event, which shows sunspots and doesn&#8217;t require looking into an eyepiece.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SunspotterCropped.png\"><img loading=\"lazy\" decoding=\"async\" width=\"928\" height=\"1024\" src=\"https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SunspotterCropped-928x1024.png\" alt=\"\" class=\"wp-image-1377\" srcset=\"https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SunspotterCropped-928x1024.png 928w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SunspotterCropped-272x300.png 272w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SunspotterCropped-768x847.png 768w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SunspotterCropped-1393x1536.png 1393w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SunspotterCropped-1857x2048.png 1857w\" sizes=\"(max-width: 928px) 100vw, 928px\" \/><\/a><figcaption class=\"wp-element-caption\">Our Sunspotter telescope provides a view of sunspots on the photosphere that can be viewed by people who have trouble looking through a telescope eyepiece; for example very young children.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What you can expect to see<\/h2>\n\n\n\n<p>We will offer you views of two of the sun&#8217;s atmospheric layers, showing features caused by the sun&#8217;s dynamic magnetic activity.

Through our hydrogen-alpha solar telescope, you will view the sun&#8217;s <a href=\"https:\/\/solarscience.msfc.nasa.gov\/feature2.shtml\">chromosphere<\/a> &#8211; a dimmer atmospheric layer than can only be seen by filtering out all the light except the red emitted by hot hydrogen. The chromosphere shows <a href=\"https:\/\/en.wikipedia.org\/wiki\/Solar_prominence\">prominences and filaments<\/a>, which are protrusions of plasma. A web-like pattern covers the chromosphere, outlining <a href=\"https:\/\/en.wikipedia.org\/wiki\/Supergranulation\">supergranules<\/a>. You may also see <a href=\"https:\/\/en.wikipedia.org\/wiki\/Solar_plage\">plages<\/a>, which are bright areas usually surrounding sunspots.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SDO-HMI-continuum-2024-05-14-rotated-1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"795\" height=\"590\" src=\"https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SDO-HMI-continuum-2024-05-14-rotated-1.jpg\" alt=\"\" class=\"wp-image-1362\" srcset=\"https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SDO-HMI-continuum-2024-05-14-rotated-1.jpg 795w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SDO-HMI-continuum-2024-05-14-rotated-1-300x223.jpg 300w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SDO-HMI-continuum-2024-05-14-rotated-1-768x570.jpg 768w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/SDO-HMI-continuum-2024-05-14-rotated-1-404x300.jpg 404w\" sizes=\"(max-width: 795px) 100vw, 795px\" \/><\/a><figcaption class=\"wp-element-caption\">Sunspots visible on the photosphere of the sun, as imaged by NASA&#8217;s Solar Dynamics Observatory (SDO) on May 14, 2024.<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/UPEI-H-alpha-2024-05-14.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"766\" src=\"https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/UPEI-H-alpha-2024-05-14-1024x766.png\" alt=\"\" class=\"wp-image-1363\" srcset=\"https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/UPEI-H-alpha-2024-05-14-1024x766.png 1024w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/UPEI-H-alpha-2024-05-14-300x225.png 300w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/UPEI-H-alpha-2024-05-14-768x575.png 768w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/UPEI-H-alpha-2024-05-14-401x300.png 401w, https:\/\/projects.upei.ca\/astronomy\/files\/2024\/05\/UPEI-H-alpha-2024-05-14.png 1304w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">The sun&#8217;s chromosphere (viewed through a red solar filter), showing dark filaments and bright plages on the solar disk, and prominences protruding along the edge.
