Fall has finally arrived, and I am indeed happy. I know the official start of Fall was over a month ago, but the weather hasn't really caught up with the fact here until today. It is brisk and sunny outside, and now the season for good observing can truly get underway.
Apparently the Sun is happy about it as well, since it seems to have decided to put on a show celebrating the change of weather patterns. Check it out:

Here we're seeing the Sun in white light, or the kind of light we normally see. If we look in a different wavelength...say, ultraviolet...the sunspot regions show amazing amounts of activity.

To safely view the Sun, use:
- an ENDCAP solar filter on a telescope
- Arc welder's glass #14
- Solar Eclipse glasses
- Eyepiece solar filters (they can overheat and break)
- Shades of arc welder's glass other than #14 (not enough protection!)
- Regular or prescription sunglasses (even if they block UV, that is not enough protection!)
- Exposed film
- Viewing the Sun low to the horizon when it appears red (this is NEVER safe!)
And right now, the Sun is giving us a whole lotta lovin'. Enjoy!
Until next time...
Carpe Diem! :D (and Noctem too!)
