Sol in H⍺ - 16 June 2021

[Hughsie]

Finally, I have caught up with all my Solar data. I have been burning the candle at both ends using my RC8 during the night time on a DSO project I am working on then switching to solar imaging during the day. The clouds now surrounding me are a welcome respite.

16 June 2021 has AR12833 as the only major source of activity, however, the prominences were superb once again and so here is a summary of my session.

 

 

Images 1 & 2 - AR12833 classified HSX. The first is taken using a 2.5x Powermate and rotated to horizontal. The second is taken using a 3x barlow showing its true position on the disc (East to the left, North up).

          

 

Images 3 & 4 - Prominence on the North East limb and estimate of its height.

          

 

Images 5 & 6 - Prominence on the North West limb and another estimate of its height.

          

 

Images 7 & 8 - A lovely prominence on the South West limb. For some reason I seem to find some really good proms in this area.

          

 

Well, we may as well throw in some moving parts too....

 

North West Prom appear to be doing the ‘twist' - 

 

Of course we can’t leave out that beautiful South West prom -

 

Have a good weekend all.

Excellent!

Love the delicacy of your prom animations.

[Hughsie]

Thank you Rusted. Are you going to give an animation a go soon? 
Clouded out these last few days but hopefully the clear skies will return soon.

Hi John,

Solid rain here too.

I've had no luck so far. Despite hours of trying with PIPP.
All I get is a continuous still for the duration of the animation.

I've tried both GIF and AVI with different source material. It made no difference.
The PIPP screen with the number of frames, etc, looks fine.
It just doesn't move!

I must be doing something silly.
I wouldn't mind it it hopped all over the screen and flashed on and off.
Once I got it going I could fix the rest.

Hi Rusted, not sure this will help but it could prove useful.

1) Before I use PIPP, I align the individual images in ImPPG. Open ImPPG > Select ‘Tools’ then ‘Align Image Sequence’. Select ‘Add files’ then choose the images files. I leave it at ‘Crop to intersection’ and ‘Stabilise high-contrast features’ then choose where I want to to save the aligned files. Hit ‘Start Processing’.

2) Open PIPP, Make sure the ‘Image Files’ tab is selected and click ‘add image files’. Choose the ones saved from ImPPG. It should come produce a pop up to say it will use ‘Join Mode’.

3) Next go to the ‘Animation Options’ tab. Here I either leave it as is or select the option to ‘Reverse Play’. Sometimes its good to see it run forward and backwards, sometimes its just too confusing!

4) Moving on to the ‘Output Options’ here I choose ‘Animated Gif’ as the output format, choose your directory where the Gif is to be saved and any sub directory (I tend to not use a sub directory).

5) Staying on the ‘Output Options’ tab, having selected ‘Animated Gif’ you then have options on the right hand side. I select ‘Loop frames repeatedly’ and then change the frame rate from 3.0 to 15 or maybe longer, say 20 (personal taste).

6) Then it is off to the ‘Do Processing’ tab. Ensure that the ‘Open output folder when complete’ is selected so you can view the Gif file and hit ‘Start Processing’.

When I open the Gif on my PC desktop it starts straight away. However, on my mac it doesn’t and I just get a still image. With both PC and mac I found that if I right click on the file and select ‘Open with' then choose my web browser it works ok. It might be just this last bit that you need to do.

Good luck,

 

John
