Saturday 17th July

Well after a week of cloud, rain and gales - good old British summer weather! this morning promised the best chance of some sun, probably for the weekend as a whole. I only managed to image for a shade over 90 seconds before the cloud, and shortly thereafter, the rain returned.In terms of todays sun, AR11087 is now in the north western quadrant of the sun, and while not as active as it has been still has plenty of detail and structure, surrounded by a huge area of disturbed chromosphere. Lots of small bitty filaments all over the disk, with a possible area of brightened plage in the north east quadrant. Of interest in the days ahead is a new area of activity coming over the south eastern limb - this is manifesting itself as an area of very bright, if small stubby, prominences - definitely something to keep an eye on. There were numerous other proms visible, however these haven't shown up great on this 'one shot' full disk image.


I thought i'd put an 'earth for scale' on the image info - boy we live on a small planet! You can click on the images to open an enlarged version in another window.
Hope you like them! Hope to get somemore captures if the clouds break this afternoon.
