The Sun in White Light 19th Apr 2016

Quick grab on my lunch break. Pretty awful seeing and some passing clouds but better than nowt :biggrin: Had to get the lappy out and use EOS Utils Live View to focus, due in part to the relatively small spots and partly to bad seeing. Forecast looks good for another one tomorrow but suspect the disk will be looking a bit bare.

Thanks guys. I was lucky to be able to get home for a bit around lunch.

I can fully empathise with the focussing issue.  Tomorrow here, there is a Solar disk pass of the ISS so I'm hoping to try and nab that.  I am in the 6km wide 'window of opportunity'.

Good luck with that, hope you get a good clear shot.

Thanks Charl, hopefully your clouds will depart soon.

Just done a few parting shots of AR2529 between the clouds, seeing really bad here.

Look forward to that. I managed to grab some Ca-K so hoping to have a full disk to show for that later, although with the seeing the way it was I am not holding my breath!

Nice to see the AR still hanging on in there.. I hope something else turns up in the next few days ... out of interest how does the size of the two small spots compare to Mercury I'm still trying to work out what to do for the transit...

According to S@N Mercury's shadow will appear at just 12" across or 1/150th the apparent diameter of the Sun.  Mercury will move its own diameter every 3 minutes.

I do. At my location it is 15:53:27 and lasts for 0.4 seconds!

I saw the transit of Venus in 2004, based on that I am expecting Mercury to be similar in size to the small spot in the upper left quadrant of this image, maybe a little larger.

Thanks both... If that's the case then the plan should work "weather" permitting...

Peter...

Oooo im buzzing around York tomorrow too... but it's probably a bit too far north for a little 0.4 second detour..

I wish you the best of luck in catching it Chris, would like to see that tomorrow afternoon..

Nice part of the world within that 6km window you have also..

Thanks

Fozzie
