The Dutch Observatory

A week and a half ago I received a request from someone in Ohio whose son was doing a school project on the Sun.  He wanted to measure the locations of Sun spots on different days and measure how they changed over time so he could calculate the rotation period of the Sun.  In order to do so he asked for permission to use some of my images.   Now everyone knows that you can use my images for any purpose, and I submit my images to the Association of Lunar and Planetary Observers, but this request for a student project made me really feel great!   Today I received the final version of the data he measured and used in the project and I would like to share this with everyone.  Congratulations Mickey with this project, and thanks for allowing me to share it here.  You did a real great job at this!!

A nice clear day again to image the sun.  Only two major active regions 1408 ans 1410.  It seemed more quiet than yesterday, but I observed a few small flares around AR1410.  A nice prominence at the western limb made a nice display.  Today a full disk image and a closeup of regions 1410 and 1408.
