Love the website, love the images. Is there a way for me to download already-made videos rather than take up bandwidth/time making a new one?
Cheers, and keep up the great work!

Thanks for the comment! There is a way to download pre-made movies. If you scroll through the user video gallery at the bottom-right of the screen, you can view any of those in YouTube, and for many of them there will be a link in the video comment where you can download a high-quality version of the same video. In the future we will also be adding a dedicated video gallery where you can browse and watch all of the different videos created and shared on Helioviewer.org. In the mean-time we’re also taking steps to try and cut down the time it takes to create movies so that you won’t have to wait so long for a movie on particularly busy days like yesterday.

Is there a way to cancel movie requests? Many of us are exploring Helioviewer, clicking on the movie button not realizing the resource demand we’re creating!
Helioviewer is amazing, fun, educational and easy to use.

I’m glad that you find the site enjoyable to use! Unfortunately there is currently no way to cancel an existing request. This is the first time we have experienced such a surge in requests, so before then there was never a need, but not it is quite obvious. We are also going to make other changes to try and make the site more useful for other things than making movies. For example, we will add a searchable gallery of existing videos created by other users, and will add a visual glossary describing some of the science surrounding the phenomena you see in the movies. We want to make the site as fun and engaging as possible. If you have other suggestions, feel free to let us know 🙂

First of all, this site is great! Very intuitive and interactive interface. I will be watching the sun here from now on.
A few questions/comments that I hope you can answer/consider:
Question 1: what are the different “instruments” and numbers (selectable from the drop down)… are those wavelengths of light?
Question 2: (Related to question 1) If the instruments are sensing intensity of a certain band of electromagnetic radiation outside of the visible range, what determines the color/intensity of the pixels we see in the images? Is it intensity, wavelengh, or both? Or neither?
Comment 1: (as my excitement grows, so does my “feature greed”) Not sure if this is possible/practical, but two improvements I wanted to suggest are:
1) It would be nice to be able to manipulate the layer order (unless you already can and I just don’t see how).
2) It would be really cool if the alpha channel of the pixels in the images were set to reflect intensity (darker = more transparent) this way, when layering different data, dark areas of one layer do not mute the information in another.
Anyway, great job!!

I’m glad you are enjoying the site!
1) The instruments listed are the names of the instruments onboard the different observatories (currently all of which are spacecraft, although ground-based solar observatories exist as well). Each observatory typically has several or more instruments, each of which collects data in one or more different ways. Often the instruments collect data in several wavelengths, which is what you are seeing when you select “171” or “304”, etc. So for most instruments you are correct: the measurements are wavelengths. In other cases though, the measurement may be something different, as is the case for the MDI magnetograms. One of the things we are going to be working on soon that should help to clarify things much more is a visual glossary of all of the terminology (instrument names, solar events, etc) that are relevant to the site. Hopefully this will be online within the next few months.
2) That’s a really interesting idea. It can be a little bit tricky since sometimes the darker areas are the areas you are interested in, but perhaps there is some more intellegent way to set the transparency, based on the content of the images.
Thanks for the feedback and suggestions!

I have found the helioviewer amazing to look at….could you please tell me what is out to the right side of the sun sometimes in the photos…the round oject….it was on the pictures I saw today 7-11-2011

Exactly what time, and which image layers (e.g. LASCO C2) are you viewing when you see the object? You may be seeing a planet.

Excelente Sitio, jamás pensé encontrar algo similar. Me comunicó desde Manizales-Colombia y mis inquietudes son las siguientes:
1.- Cuanto tiempo lleva el proyecto Heliviewer trabajando.
2.- Que entidad lo patrocina, estatal?, privada?.
3.- Con respecto a la (2) pregunta, la inquietud es por que pueden manipular las imagenes cuando aparezcan UFOS.
4.- Podremos ver gracias a Helioviewer el paso del cometa Elenin?, y podremos decifrar tambien que viene atras de su cola?.

Hi Keith, in case you need more help to understand Spanish, here it goes what Edison Loaiza said:
Excellent website, I’d never thought I would find something similar. I’m writing from Manizales-Colombia and I’m interested on the following:
1.- For how long Helioviewer has been running?
2.- Who or which organization supports it? governmental? private?
3.- the second question is to find out if the images would be pro-processed in case of UFOs being observed.
4.- Could we watch the comet Elenin using helioviewer? Could we also understand what goes behind his tail?
Thanks a lot!!

Thanks, David! 🙂
Edison, sorry but I’m afraid I can only reply in English. First off, I’m glad that you enjoy the website and it’s good to see new visitors!
1) Helioviewer has been under development for over three years now, but it is only in the past year or so that we have reached a stable point in our development and have begun sharing the project with others.
2) The Helioviewer Project is developed at ESA and NASA.
3) The images are processed from the original data in order to make them more clear, but no parts of the images have been added or removed. Occasionally you will see problems with the images (especially, for example, STEREO COR images) which make it seem like there is a UFO, but this is in fact only a defect of the camera.
4) Unfortunately Helioviewer.org does not currently include any of the instruments which will see Elenin in the near future. However, STEREO HI will see it between Aug 1-12. I will try and link to some images on our blog when that happens. In the meantime, check out http://www.universetoday.com/87619/worried-about-comet-elenin-faqs-from-ian-musgrave/ for some more information.

This site is frick’n awesome! Thanks loads! 🙂

Thanks for your excellent projet.
Could you tell me why LASCO C2 and C3 images are out of date since 2012/12/04 at 09:18:06 in Helioviwer.
Thanks a lot!!

hi all, recently their has been a large object by the sun, i put this picture on youtube, but do any of you know what it is, its on lezlow111 youtube, cheers
#15 by Eber on June 23, 2013 - 2:38 am
Hi, congratulation for the amazing work. My question is about the giant suppost UFO that appear near the sun surface, left side, in the bottom, who looks like getting energy from the sun. I saw it many times, ever in the same place, but specially on 2012_03_08 until 2013_03_11. Can you explain that?
Have a nice day!

Where can I put my video?? It’s very interesting.. and i want to share with others.

When I first found HV it would load each time. One day it stopped loading and has never loaded since. I’ve tried to access the site with two different connections. Never loads anymore and wondering why. I also tried some troubleshooting specifically for that site. Nothing but the black background and disabled icons.
