There have been few studies done regarding animal behavior during an eclipse, although there have been many anecdotal stories. There was a study done after an eclipse in 1932, and that revealed some information. Still, although we know something about how animals behave, we don't know that much, and we don't know why.

Their behavior seems to fall into one of three categories: going through their nighttime routine, active and afraid, doing nothing different. This behavior covers all creatures, from insects to mammals. There are several studies planned for the eclipse coming next week.

With my weak eyesight, I missed the reference to the Lunt 60 in your first post. Sorry about that. And I had already made a b&w (grayscale) of your photo [see attached], but I was just wondering if if your original data might have had a bit more detail. So, thanks for sending that, too.

On the photo section I enlarged and enhanced, one can see what I believe is a filament that shows up because we are looking straight down on top of a prominence. Is this your thought, too.

What I was wondering about when I asked about the filter was how good the filter was? In particular, did the blocked wavelength regions match where the camera's sensor was sensitive so that only the 393..4 nm line came through to the sensor. One does not want any of the near infrared region nor the long wavelength ultraviolet to get the sensor or the sensor would record that unwanted light.

BTW, the specs for the Lunt 60 claim a bandpass of 2.2 A. I have not done the calculation yet, but I was wondering if that is wide enough that the blue- and Doppler effects of the rotating edges of the Sun's disk are still within the filter's allowed region or not.

That might be an interesting calculation if one is interested in that kind of detail.

Thanks again for your helpful data. --Richard

I like seeing the Sun in the H-alpha line. It clearly shows the granulation in the photosphere. Thanks for sharing this neat photo. BTW, if you don't mind sharing, what brand and model of filter did you use?

Hey, could you also post a less processed image? For example, one without the reddish tone in the corona to the outside of the sun's disk and simply in grayscale? I was trying to see more details in the prominences, and I'm guessing we would see more with no coloration. Or on second thought, it may be better to see the disturbances on the Sun's surface in visible light. Whatt do you think? --Richard

Are you tired of taking care of the old, sick mice in your house? Science has come to the rescue!

"Turning back the clock

An experimental treatment rejuvenates the immune system of older mice, improving the animals’ ability to fight infections. A week after receiving an antibody injection, old mice had about 38 per cent fewer aberrant stem cells than rodents of the same age that didn’t receive the treatment. They also had greater amounts of two types of white blood cells crucial for recognising and combating pathogens, as well as lower levels of inflammation. If the approach works in humans, the therapy could reverse age-related declines in immunity that leave older adults susceptible to disease."

If they can perfect that for humans, that would be fantastic.
