Citizen Science

Post by Carbon60 » Thu Nov 22, 2018 7:15 am

Dear all,

Everyone enjoys our pretty pictures, many of which are stunningly detailed and breathtaking, or in animated form display the structure and dynamics of plasma flow on a grand scale. We may now have a chance to contribute to solar science. From violet to red we cover the spectrum, at all scales, as a global network of motivated enthusiasts. Whether full disk, or magnified view of an active region, or images of filaments, prominences, granulation, flares, sunspots (genesis, evolution and decay) there’s usually a forum member somewhere on the planet capturing data to record the event.

What we record is useful scientific data. In the New Year Alexandra, Mark and I will be meeting with one of the UKs leading solar research teams in London to discuss just how useful our data might be, even in a world with SDO, Big Bear and DOT. For this I’m hoping to impress them with our abilities and achievements on SolarChat and with this I’m appealing for your help.

What I need for the slide deck presentation are examples of your best images in any light and at any scale: stills, animations, SHG analyses and so forth to really showcase what we can bring to the scientific community as a powerful global team.

If you are interested in contributing to science, please post your best images to this thread for easy access for me to download. I will, of course, make the final slides available to anyone wishing to use them for similar purposes.

I think this is an exciting opportunity for us all and I thank you all in advance for your contributions.

Best regards

Stu.

Stu: I think it is a great idea. I am very happy you and Alexandra are taking the lead on this. Not sure my images will be up to the task but I am willing to give it a try. At our observatory a team does occultations and that is a contribution to science. Some images to follow....

Franco, your images will always be up to the task. If you imaged it then you have captured it! What is more vital is that you know the time and date. I always have the camera settings in Firecapture set so the file is automatically time and date stamped then that bit is sorted.

Stu and Alexandra...

Sounds good to me!!!

This reminds me of the days when I had more time and made regular submissions (primarily Mars and Jupiter) to support NASA/JPL/ALPO/Hubble programs. It would be great to have the solar observations utilized as well.

I’d love to contribute in some meaningful way. I’m wondering if there are some image processing guidelines we should follow to preserve the scientific value of the data. I keep all my image capture logs. Thank you for taking point and please keep us posted.

Dear Stu, Mark, and Alexandra,

that is an excellent initiative. In this forum there is worldwide expertise at a very high level available so chances to obtain interesting data for science may be quite good. The question will actually be where - from the professionals - the interests are, and if there is a sufficient number of contributors here willing to submit images.

Beeing a (non-astronomical) imaging scientist myself I would expect, however, that for a real pro-am collaboration the aim will bo more to produce scientific data (=picture) quality rather than "pretty pictures". Also, some standardization of the imaging and postprocessing may be required.

A lot of excellent image material from the amatuer community is already available at repositories such as the ALPO Solar Archives (http://alpo-astronomy.org/gallery3/inde ... ns-Archive ), or the International Solar Database (http://solardatabase.free.fr/demande_par_mail_en.html). At least from ALPO I know that they aim at pro-am collaboration as well, but to me it appears to be more amateur driven and I have a hard time to identify useful scientific data drawn by professionals from these databases. However, this can be just ignorance and incomplete knowledge from my side :P

Anyway, I would be happy to contribute. Below please find some image material from myself which I have presented on this forum earlier.

Good luck for your inititiative and let us know if you need support!

Best wishes,
Laura

Hi Stu & Alexandra,

excellent idea but I agree completely with Laura. Going for science if very different from the Pretty Picture stuff. That (and some other discussions on this forum latelely) made me lean towards things where contribution to science is still possible. (Variables, Minor Planet light curves ...) Still a lot of studywork and equipment change needed.

If contribution to solar work is possible, I will for sure do the needed observations, if within my budget. (I have time) There are opportunities, see this project http://fchroma.astro.uni.wroc.pl/index. ... guide.html and there tuturial. A pitty it stopped after this one.

Regards,

Paul

Dear Alexandra and Stu,

I am excited to hear that you are looking into the possibility of extending our contribution to citizen science.

I am able to contribute with high-resolution H-alpha, Calcium-K and G-band images.

Here is an example for H-Alpha imaging:

The M-Class flare on 23 Jul 16 captured with an ARIES D-ERF on a CELESTRON 150mm refractor was featured in an article "Recruiting flare hunters for citizen science" by by F-CHROMA. You can read the article at: http://www.fchroma.org/files/agfhunters.pdf

You can also view an animation of the flaring sequence taken by me at: https://twitter.com/yltansg/status/924129488148901888

These images were featured in the News & Reviews in Astronomy & Geophysics Volume 58, Issue 6
December 2017 ISSN 1366-8781 EISSN 1468-4004.

For G-band images, I hope to contribute something like the following:

All the best in your coming meeting with the research team in London.

Hi Stu.

Well done! I applaud what you, Mark and Alexandra are planning. There seems to be a pretty active pro-am collaboration in stellar spectroscopy and it would be exciting to see something similar happen with solar observations. It would definitely be interesting to find out if there is some niche which amateur solar imagers could contribute to that isn't covered by the professional terrestrial and extra-terrestrial telescopes that continually monitor the Sun.

There are many exquisite filtergram images available from the members of this community, much finer than my own. I'd be happy to provide some spectroheliograms for you to include in your presentation. I've done a number of projects with the SHG to measure, for example, velocity fields in prominences and on the disk, solar rotation, magnetic fields and filament temperatures. These kinds of studies are interesting to me but probably irrelevant to solar researchers who have their own specific analyses to apply. The images I've included here will give an idea of the kinds of raw data that an amateur spectroheliograph can yeld. Hopefully they'll be useful to your proposal.

Here is a montage showing the basic strength of spectroheliography: imaging at a specific wavelength of choice.

The next two images use the dopplergram technique to highlight velocity information which is easily accessible in the processing steps required to generate any spectroheliogram.

Of course, basic spectroscopy is also an option with a spectroheliograph!

I have to say, I’m deeply impressed and humbled by the response from everyone; but then again your keenness to support this initiative was really only to be expected, as we are a highly motivated and very capable community. The interest expressed here in contributing to solar science speaks volumes.

For those of you on the sidelines, please make yourselves known as this has to be totally inclusive. Everyone must know that they can participate.

Anyhow, I’m on business in the US this week and so access for me will be limited until I return to the UK this weekend. In the meantime please continue to showcase.

I hope to pull something together during December.

Really excellent work, everyone.

Stu.

Alexandra and Stuart...

I too had a look though images from a few years back in the midst of the peak in activity, most of these coming from 2014 and 2015. I included a variety of WL/CaK/Ha images taken through several scopes and filters. It was nice getting a look at these images again, and some stood out even after a few years since capture.

Lots of stunning images here. Thanks everyone.

I’ll work with a Alexandra and Mark to pull a slideshow together over the coming weeks, aiming to showcase our capabilities.

It will be interesting to hear what the experts say and, learn about what they require.


Best to all.
