Thanks for the kind words guys..................... keeps me motivated to fight the dire conditions that have plagued this part of the world for most of this year!

grimble_cornet

Your experience matched mine exactly Stu..................... just a large enough gap in the grey grot to capture a few images

The gap closed before I could take a look in Calcium K or white light so... nice to see you managed at least 2 'lights'

grimble_cornet

Cheers Mark. It was 'touch and go' with a few missed captures. One of those 'right time, right place' events where the 20 minutes of intermittent sunshine coincided with the little surge prom doing its stuff. I'm still amazed how well the Lyra 152 with its full aperture ERF works in really pretty po...

grimble_cornet

Superb images Ale - the new setup is working very well

Just a few hazy gaps in the overcast this morning but I managed to get about 20 minutes (with a few breaks). A very nice prominence on the Eastern limb and an even nicer 'spurt prom' as a goodbye wave from AS12683 Lyra 152 Quark Grasshopper3 0810 2017 1013 ut.jpg Lyra 152 Quark Grasshopper3 0810 201...

Thanks for the kind words guys. Eric; Stu (Carbon60) did all of the hard work designing and developing the magnetometer I use. If you are interested, the whole story of how it was built, tested and developed is told in the following SolarChat topic: https://solarchatforum.com/viewtopic.php?f=8&t...

The usual depression after getting a Red Alert Arora warning on a wet and cloudy night :roll: :evil: :roll: But satisfaction as the high speed solar wind produces a massive kick on my magnetometer: Solar Storm September 27th 2017.jpg Hopefully the image is easy to understand: Top part is the warning...

grimble_cornet

Thanks guys :bow2 Not a bad comparison Stu. Here's our data plus that from a range of UK stations for comparison: Magnetometer comparisons.jpg I'm very happy with my results now, other than the 'ramping up' from a low value at the start of the day. I often get similar effects - thought it was a temp...

Thanks Alexandra. I had imaged the X class event earlier on September 6th: AR12673 flaring -Tal 100 Quark Grasshopper3 0609 2017 1055 ut coloured Mark Red.jpg So, I was quite keen to see what would show up on my magnetometer record a few days later and was excited when I saw a nice peak on the scree...

Simply stunning work

A small 'cloud' of high density plasma passed close to Earth at about 2100 ut on 22nd September: Radial Velocity.jpg I was interested to see how well my magnetometer would respond; especially as after having some serious issues, I had just finished giving it a 'service'. Combined data 22nd Sept 2017...

grimble_cornet

Pretty dire conditions yesterday but managed a few minutes 'fishing in the hazy cracks between the clouds' in the afternoon. Seeing was appalling and even focussing the Tal 100 + Quark combo was a struggle. By using x2 binning I was able to capture enough data for a pretty grotty FD mosaic: Tal 100 ...

grimble_cornet

Good stuff Stu. I had very much the same experience yesterday with Ha being very difficult and CaK not much better! The Tal 100mm f10 has pretty much become my 'grab and hope' scope in these times of dire seeing. When combined with the Quark, it seems to cope with poor seeing far better than my Lunt...

grimble_cornet

Thanks guys !

grimble_cornet

Great collection.................. always get a smile from CaK proms

grimble_cornet

Lots of sunshine and even more haze but couldn't resist a few shots with the trusty Tal 100 plus Quark Chromosphere: Tal Quark Grasshopper 2017 1406 1048 ut 4 pane mosaic.jpg Tal Quark Grasshopper 2017 1406 1048 ut 4 pane mosaic coloured.jpg A 4-pane mosaic showing 2662 and a superb collection of pr...

grimble_cornet

I'll have to agree with Mark and Pedro (as always) and say that Firecapture blows away any other capture programme I have tried and that using FlyCap for solar imaging would drive me mad! I'm not sure which model Grasshopper you are using so this may or may not be relevant: Before I got my Grasshopp...

grimble_cornet

Despite the Aurora Watch UK emails over the last 24 hours.............. No realistic chance of seeing the aurora from where I live but....... the trusty home made magnetometer allows me to see what I'm missing: Report on the solar storm from the SOLARHAM website 1-2 March 2017 Space Weather.jpg And ...

grimble_cornet

Thanks for the kind words guys.
Back to normal today with strong winds, rain and even a few snow flurries !!!!

grimble_cornet

Great set of images Matt.
Good to see somebody else getting to image the sun again!
At least our days are getting longer now in the UK so; more chances to observe the sun at a reasonable altitude.

grimble_cornet

Thanks guys ........ it was good to see the sun through a scope again. Stu: the storm seemed to have improved things as the atmosphere was quite steady at mid-morning and was just starting to 'shimmer' a little as the clouds rolled in at lunchtime. Pity about the haze which really took the edge off ...

grimble_cornet

First Solar imaging session of 2017 - frightening, but indicative of the wonderful conditions in the UK so far this year!!!! Not brilliant conditions with haze and thin cloud obscuring the low morning sun but; managed to grab a few images before the clouds rolled in. Using the Tal 100, Quark and Gra...

grimble_cornet

Great set of disks Eric - they show off the filaments and proms very well.

grimble_cornet

Great set of images in 3 bands. As far as the white lights are concerned........ Difficult to compare images with slightly different brightness/contrast etc so I copied the interesting bits from images 1+5 and 2+6 and pasted them side by side in PS: 1 plus 5.jpg 2 plus 6.jpg I still find it difficul...

grimble_cornet

Thanks for the kind words guys - much appreciated

My imaging window is very narrow at this time of year and a large clump of 15 feet high bamboo is reducing it even more. I feel a pruning session coming on

grimble_cornet

Love the transit!

grimble_cornet

Thanks Franco....... just a short time lapse saved as a gif file.

grimble_cornet

Hi Paul.
I have had similar problems in the past when I stayed out for several hours in very cold conditions, but today was only about 4 degrees C and I was only imaging for about an hour.

grimble_cornet

First time in weeks that the sky has been clear as the Sun passed through my 'Winter window' Very low sun, frost on the ground and haze but................... a chance to image not to be missed. First up: the Tal 100, Lunt CaK1200 and Grasshopper: Tal100 CaK1200 Grasshopper 2016 0112 1054 ut.jpg Tal...

Beautiful CaK shot Stu - never realised how pretty a blank disc could look

grimble_cornet

Lots of magnetic activity this week as a group of coronal holes moved into an Earth-facing position. The high solar wind speed and moderate (G2) magnetic storming generated lots of auroral activity with several amber and red alerts in the UK but, as usual, the clouds got in the way :roll: Fortunatel...

grimble_cornet

Great catch

grimble_cornet

Yeah......... I know the feeling (me, not my computer) :lol: For what its worth........ I have been using Windows 10 for several months now without any real problems. All the usual programmes seem to work very well with all of my mounts and camera (EQMod, PHD Guiding, Nebulosity, Firecapture, Genika...

grimble_cornet

Nice image David. Have you looked at the fan in your pc? I hardly ever use a pc these days but in the past have been amazed at how much crud built up around the fan/input grill etc. hence the overheating issues I was having. A simple de-fluff and all was well. Sorry if I'm trying to tell grannie how...

grimble_cornet

Just seems like a nice idea......... although it is interesting to compare results from different commercial stations and see magnetic changes happening at different times and to different degrees of intensity.

grimble_cornet

Great news Mark

grimble_cornet

Impressive as always Eric.
Really like how you have made the filaments stand out from the disc in the inverted images.

grimble_cornet

Exactly as Pedro said - works in Firefox, Microsoft Edge and Internet Explorer. You get a larger image with a '+' (magnifying glass) to click for full size if the image is very large.

grimble_cornet

Thanks guys.......
Its good to have something to look at when the weather is frustrating and the Sun is 'quiet' visually

grimble_cornet

Fabulous Derek - thanks for sharing these gorgeous images.

grimble_cornet

A great catch........ and its certainly big:

Its pretty frustrating getting Aurora Alerts when you live in 'Cloudland' UK but at least the trusty magnetometer has been enjoying the show over the last couple of days as the solar winds have been blowing through:

Welcome to the SolarChat Magnetometer Network.
As Stu said........ we need a few more to cover the globe

grimble_cornet

That DS is looking really good mate!

grimble_cornet

Stunning work Jozef

grimble_cornet

Looks like you had a pretty good SUNday for a change

I had a similar 'oh no' moment with my extensive clump of bamboo the other day - guess its out with the ladder and the loppers to reduce this year's growth from 15 feet down to about 10 to allow me to image into the Autumn

grimble_cornet

A great pair of FDs David

grimble_cornet

Well worth the wait Steve - great presentation as always.

grimble_cornet

Some very nice detail in all wavelengths Pedro - thanks for sharing.
