August 4th Ha and Midnight Lightning

Post by MapleRidge » Sat Aug 04, 2018 11:03 pm

Hi all...

I has a clear start to the day but a lot of cloud began to drift in after I nicely started to image. I was able to grab a few full disk and higher resolution Ha images before I was shut down for an hour or so. There were not a lot of features today, the remains of AR2717 and a region starting to rotate into view were the main features. There were no proms of any significance while I was imaging so I finished up before the clouds.

The first is a single full disk image through the LS80T/LS75FHa/B120Ha solar scope:

The high res images were taken through the modded CR150/DSII/B1800Ha scope. The first has the pressure in the DSII etalon at 0 PSI, mimicking a deep red 'visual' filtered image. There is still a trace of a few small dark pores in the region, shown as both positive and negative images:

The final Ha images are from the eastern limb where there appears to be some emerging activity. The images below are a 3 frame mosaic:

As is typical, after I closed up the observatory and went in to work for a few hours the sun came out :o

The midnight lightning in the topic refers to my session last night. I headed out to take a crack at imaging Mars, but there was frequent cloudy periods that obscured mars and I could hear thunder in the distance. I started to see some lightning obscured by clouds in the north, so I pout the DSLR on a tripod and began to gram images with the hopes of catching some lightning. As it turned out eh actual storm was 100Km (60 miles) to the north and all I was seeing was the discharge illuminated clouds. I finish grabbing images just before midnight and was pleasantly surprised how nicely the storms progress was shown in the pics (plus on little bolt of lightning ) as it drifted to the east. The stars of the big dipper are seen slowly drifting down and are hidden by clouds near the end of the video clip. The video was assembled form 50 x 15sec exposures...click the icon below to open the clip.

It is to be clear tonight, so maybe I will have more luck with Mars this time ;)

As always, questions and comments are welcome.

Nice shots Brian, the new activity on the limb should give us something to focus on for a couple of weeks. The lightning video is well cool!

Thanks Mark, let's hope this emerging region develops into something with some nice activity!!!

Sounds like the video loaded...wasn't sure if it was going to play outside of my own PC.

Cheers Brian my iPad won,t download the video but good to see you getting some pics.I have started the bees again and they have put Honey in over winter in the coastal areas (less than 4km from the ocean)so I am flat out for a while.It has been a dry warm winter which is good for me but not for those inland in other agricultural pursuits.

Thanks for your feedback Derek :bow

We have been having a relatively hot and dry summer here, though the drought broke in time to save the corn and beans for a few weeks at least. Dry weather has cut wheat hay yields, in some cases as much as 20%.

A great crop of images, Brian. No luck with the Video on my iPad though; just a blank screen.

Thanks Stu!!!

I will try to post the video to YouTube...the IPads seem to have an issue with it.

I have added a link to the thunder storm animation...hopefully that will come up on the iPads. Mine is at the office so I can't test it out.

Nice shots, Brian.
That lightning video is pretty cool. We’ve had some pretty spectacular storms here lately. You’re inspiring me to try some filming!
Cheers, Peter.
