Re: Mercury-Solar Transit Mega Thread | Nov 11th 2019

Many congratulations on a successful transit session (with your little helper). Beautiful skies and fabulous images worthy of the public interest you’re receiving: radio, NASA, Spaceweather..... there’s no stopping you.

Well done.

Re: Mercury Transit

I feel your frustration, just getting those tantalising little glimpses every so often to get things set up with precious time ticking by. The event waits for no one, ready or not.

Lovely image of the final stages. Nice scope too. :)

Very nice indeed, Eric. It was well worth the wait. Start, middle or end, it doesn’t matter so long as you got something....and you certainly did. :)

Re: Mercury run around

What a day you've had. The heavens seem to have thrown everything at you: rain, hail, more rain, thunder and lightning, but even so, you managed to capture some nice images of the event with your persistence. :) I hope you've thawed out by now. It's a pity the outreach didn't work out. I'm sure your...

Mercury Transit November 2019

I took a holiday from work today for the transit and then a 250 mile round trip to catch some half decent weather in the Midlands (UK); certainly it was a lot better than my local weather at home, which was under cloud and rain. Even so, the conditions were less than ideal with significant haze and ...

Sun in Ca II K - Bad seeing 20191110

I've been trying out a few different combinations ready for the transit tomorrow. WL was useless because of really bad seeing (I think the worst I've seen). Here's a short animated gif of the turbulence at the limb to illustrate what I mean. This is at reduced speed and limited frames (100) to keep ...

A really interesting watch, John. I love the fact that old data, collected on antique equipment, still has a scientific role to play.

Re: Anybody going to catch the Mercury Transit?

I’m hoping for the best, but expecting the worst. Reports are not looking promising. I’m planning to be mobile to chase the better weather, but even then I doubt I’ll be successful.

Good luck everyone.

Re: How to locate the Dust Bunnies

Jack, Many of these should be able to be removed from the sensor with a few blasts of compressed ‘air’ from a can. However, static charge can hold some stubborn ones back in which case a few squirts from an anti static gun (as for vinyl records) and then air blasts should remove these. Really stubbo...

Superb, Peter. Top notch science! It’s amazing just how much information spectroscopy can provide if you know how to extract it. It will be interesting to see more of this type of analysis as cycle 25 develops. You should be able to map out plage formation and development as a function of magnetic f...
