A little bit more of interest this morning.
Only the briefest of opportunity to see our local star today,and even then only in white light. There is a small spot system on view, although it is quite complex and interesting. (See SOHO image)
Again, not a lot going on.
Quite a nice filament, and the bright spot at around 10 o’clock is a tiny (un-numbered) sunspot.
Quite a nice prominence this morning
Saw the Sun again this morning! If only fleetingly between the fog, clouds and haze.
There is a tiny sunspot on view, but some rather nice prominences.
I don’t think now is a good time to buy any solar kit! No significant spots or prominences. Never seen the Sun so quiet!
I thought it might be interesting to see the transformation of a filament to a prominence over a few days. (They are the same thing, of course!). Today’s image is on the far right.
As expected, the recent large filament has now reached the solar limb and can be seen as a prominence (the one at about 3 o’clock). It isn’t spectacular, but nevertheless there is quite a good prominence display today.
Here’s a couple of the items we discussed at the last RAG meeting.
Hubble’s variable nebula, NGC2261 or C46, is only 2′ in size and therefore not really suited to the window-sill ST80. Will have a go with the SCT next time I go outside.
As a seasonal image, here is NGC2264, the Christmas tree cluster. I have turned it the right way up for anyone not familiar with it. It is a bit bigger than last-year’s version!
The star at the base of the “tree” is 15, or S, Monocerotis. The blue “halo” around it is not an entirely optical effect, as to quote Alan Macrobert in his book “Star-hopping for Back-Yard Astronomers”, it is “about as blue a star as you’ll ever see”.
