A reliably clear sky, so suitable for an animation. This animation consists of 90 frames, 60 sec apart played back at 10 frames per sec. Dave

You cannot see prominences in white light. They are clearly visible in hydrogen alpha but the kit gets very expensive. White light astrophotography is much simpler than for DSOs but you really need a different type of camera. I use an ASI174MM, which is a mono camera that can take frames at a rapid rate. The scope needs to be filtered with either Baader film, or a Herschel wedge. In white light you can see sunspots and depending how large your scope is, the details of umbra and penumbra. The software for capture and processing is mostly free. Hope this helps, please ask if you would like more detail. Dave

Thank you Peter. Iagree. Even though I could see some change as the images slowly came in, I had no idea of rotation. Dave

The prom from yesterday has virtually disappeared, but when I saw this one, thought that it was worth an animation. This runs from 0942 to 1120 UT and consists of 90 frames each separated by a minute but played back at 10 frames per sec (i.e 600 x faster) Enjoy Dave

Fantastic. Dave

Thanks Francis Dave

It certainly looked as if it was off. I find their behaviour fascinating. Thanks for the comment. Dave

That prom just cried out for an animation. Enjoy Dave

Another from this morning. Dave

With these reliable clear sky conditions doing animations becomes much more straightforward. Here are animations from the last 4 days. With the first one I noticed that AR3327 was rather bright and probably flaring so immediately started an animation run. This was on the 7 June Next day I tried a prom in the NE Encouraged by that yesterday I tried another. and here is the only big prom from today All good fun. All the "normal white light and H-alpha images will be on my website. Dave

Thank you. Do you post your sketches anywhere, I would love to see them. I am totally useless at sketching. Dave

Thank you josefk. I presume you mean the full solar disc in H-alpha. Dave

Dave

Very nice and sharp. Good work. Dave

That's a lovely group of sunspots in the NE. Well done. Dave

This last image is a mosaic of 15 frames with 3X Barlow. Click to see large version Dave

Excellent Ewan. The animation is fascinating. Dave

After a cloudy morning the sky unexpectedly cleared in the afternoon. Dave

Very nice David. Dave

Thanks David. I was lucky. It was forecast to be clear most of the morning but it rapidly changed from very thin cloud to solid cloud. Dave

Dave

Thanks David. The last one is with a 2x and 3x barlow and the best 100 frames out of 4000. Dave

Firstly in white light with a continuum filter. and finally in Halpha Time and cloud did not let me explore that floating prom in the SW Dave

Very nice, as usual. Dave

This is a mosaic of 7 frames. I can get a full disc in one but this gives so much more detail. No impressive proms today. Dave
