20090225 Sun

We have a brand new active region! Transparency is 4/10 with many thin cloud around, seeing therefore, 2/10 at best.

Borg 45ED II is used, along with my Solarmax 40 and BF10, DMK 31AF03 on my LXD55, i.e. my usual indoor setup.

1334 (GMT+8):-

1335 (GMT+8):-

Next, several shots were taken with a 2x barlows on the active region.

From 1336-1355 (GMT+8):-

Finally, I pulled out my APM Herschel wedge to see if it's detectable in white light with my small setup.

1402 (GMT+8):-

And then I pulled out my 52mm IR-pass filter to see if there's anything special in IR? Of course, from my past experience, since it's not a narrow band IR filter, it's just a special case of white light so that it's less affected by poor seeing. Let's see how it turns out.

1404 (GMT+8):-

The new AR has a number of 1013 and it should belong to cycle 24.
