31st Dec.
Another fine day but the Earth's upper atmosphere was rough and this made focusing hard.
Attached are two images to end the year.
The first shows the sunspots at 540 nm and the second the area around AR3936 near the western limb at Ha wavelength.
AR3936 has had numerous M class flares and two X class flares in the last 48 hours.
Regards to all - hope we have a good new year.
Cheers,
John W
