Hi Folks, The weather forecast shows clouds clearing later in the day tomorrow, so we'll go ahead with the star party at Lakeridge unless there's a big change in the next 36 hours. If you're planning to come, please reply to me directly (I just want a basic count of the number of scopes we'll have). Thanks! John Craig

The Sun yesterday (in a few different absorption lines)
by Dale Hooper 17 Sep '22

17 Sep '22

Hi Utah-Astronomy, A few months ago, I finished building a Sol'Ex spectroheliograph (see www.astrosurf.com/solex/sol-ex-objective-en.html) I'm using the Sol'Ex, a William Optics Z61II, a ZWO ASI 1600mmPro and a Lacerta Hershel wedge to do narrow band imaging of the Sun. I finally set up a flickr account so I thought I'd forward a link to you of some of the images I was able to take yesterday. We finally got a break from the clouds so I was able to get images in hydrogen alpha (656 nm), hydrogen beta (486 nm), the Sodium (Na) doublet (589 nm) and the highest of the Magnesium (Mg) triplet (b1) (about 518.4 nm). It looks like the focus for the hydrogen alpha image wasn't as sharp as it was for the other images. If you'd like to take a look at the images, they are at: https://flic.kr/s/aHBqjA7oBS Clear skies, Dale.

School Star Party at Lakeridge Jr. High in Orem 30 September
by John M. Craig 01 Sep '22

Hello Friends, If you're available and interested, we'd be pleased to have you bring your scope; binoculars; whatever you've got. The info from the new science teacher who'll be coordinating things for the school is below. Please email me directly and send a phone number so that I'll be able to let you know in case of inclement weather. Thanks! John Craig 801-805-4963 As in years past, we will be hosting the event on Lakeridge's track. This is located east of the school and south of the rear parking lot. This lot will be most convenient for parking as it is adjacent to the track. We will be telling students that they are welcome to come to the event anytime from *8:00 pm to 10:00 pm*. Teachers and at least one administrator will be present to help supervise and instruct students. We will be at the school at least a half hour before the event to facilitate set-up and greet any volunteers from the astronomy society. We'll have access to the school if anyone needs to use indoor facilities. We will also ensure sprinklers are turned off, as will be any nearby lights that can be turned off to enhance the viewing experience.
