Additional release of the pictures taken by the DCAM1
The other images taken by the separation camera (DCAM1) are additionally uploaded here.
Because the deployable camera 1 is separated slower than the deployable camera 2, it can take several photos from the nearer points.
We can see the shadow of the DCAM1 on the solar array panel mounted on the spacecraft body in the following image.

The following image is the animation file (GIF).
We succeed to take the detail images of the spacecraft body and the sail as follows.

We also conduct the operation check of reflection control devices which control the spacecraft attitude by changing its optical property. It can be seen that the devices are well functioning. This device is originally developed in JAXA, and thus it is the world first that the device operation is verified in the orbit.
When the devices are turned on, the incoming Sun light reflects specularly. On the other hand, the Sun light reflects diffusively when the devices are turned off, and its surface is seen more brightly white than when turned on. In this experiment, the devices are alternately turned on and off in order to easily see the difference in the taken images. It is easier to see the difference to compare A with A, B with B, and C with C. We plan to switch on/off with synchronizing the spin period in the future experiment.
