The free SunSketcher app will use your phone’s camera to record the event and help study the sun’s ‘oblateness.’

      Won’t this damage the ccd?

      Yes, which is why you need to use a solar filter.

        Don’t know if you’re joking, but just to be safe: no need for a filter

        edit: apparently I was wrong

          “When shooting still images or video of a solar eclipse, one rule is paramount: special-purpose solar filters must always remain on cameras and telescopes during the partial phases (including the annular phase of an annular eclipse).”

          It’s a good way to fry your camera. If you’re taking a single shot, you’re fine. But if you’re recording continuously, you can damage your phone’s sensor.

            Interesting. I could have sworn I read that it’s not required, but I can’t find it any of. I stand corrected.

    Here’s the map of the April eclipse across the US. It will go from Dallas Texas and curve off through Buffalo New York and maine:

      Going right through my town and I’m looking forward to it… so of course there will be total cloud cover.

        Same experience here. Meteor shower… cloudy, lunar eclipse… cloudy, Aurora… cloudy, comet that’s visible for a couple of weeks… you better believe it’ll be cloudy every day.

          Yep. Every single time.

          Okay, not every time… the times it isn’t, I would have to get up at like 4 am to see whatever it is.

        Some types of clouds dissipate right before an eclipse then come back shortly thereafter

            I do not actually know, nor do I know if that is true, but if it is, I suspect it would have to do with temperature differentials due to the sun temporarily shutting off.

    Oh I’m going to do this. I’ll have 97% at my little cabin, and my husband is going to drive a little bit east to film the totality. We were planning to film anyway, so we might as well share it with NASA.

    Is there any risk of damaging your phone/camera by pointing it directly at the sun? Or is it dim enough during the eclipse to not matter? The article doesn’t say how long you would need to point it at the sun, maybe a few minutes to an hour.

      A camera isn’t your eyes, you could point it at the sun all day.

        Nearly every photographer that comments on this issue says it is OK if you do it very briefly such as when you are taking a scenery photo and the sun is in the picture. The argument for it not being safe is that some of the more recent smartphones use larger and faster lenses (f/1.7 to f/2.0) to get better resolution, and that can be a problem. Most digital cameras have an Auto mode in which they will automatically reduce the exposure speed and increase the f/stop to take the photo, and this will not harm the camera

    Yeah I had this all set up and ready to go. As it instructed, I started it about 5 minutes before totality. It began counting down until it took the first picture. Then instead of taking pictures the app just closed/crashed.

          That’s why I bought it. Didn’t do me much good when the model I got has terrible hardware. I’ve had more responsive screens on $170 Motorola phones.
