Annular Eclipse Nobuo YAMAMOTO
However, it was a clear sky on the day contrary to expectation, so in a hurry, I made a pinhole in the flank of the cardboard box, which lay on a kitchen, by a needle and came to a parking lot of the super mall around here with a digital camera to observe the annular eclipse. By the very careless way to install a cardboard box in a trunk of a car as shown in the right figure, I took pictures of the annular eclipse projected from a pinhole blankly by a digital camera from the slanting top. The projected sun was below 4 mm of diameter and moreover lacked clearness, so a clean picture wasn't obtained of course. But still the pictures which seemed to be those of the annular eclipse somehow were obtained, so those were arranged according to the time process as shown in the following. |

From 6:59 to 7:50 a.m. in May 21 (Mon.), 2012 The pictures were projected through a pinhole. The scales of these projected pictures are about 5 mm. [Notation] it's because I took a picture of a digital camera from a slant direction manually that the size and the warp of these pictures are not fixed. |
| As a thin cumulocirrus covers the sun, choosing the time sunlight becames a little weak, direct zoom lens photography of Annular Eclipse by a digital camera was taken as shown in Fig.3. The annular eclipse in the rear of thin clouds is still taken brilliant overall by the halation due to the influence of too much brightness of the sun. But, occasionally, a small circle comes out in the right in the each picture. It is ghost. It seems that this ghost is a fairly accurate copy of the annular eclipse of the fact. By the way, the ghost which is thought to indicate the annular eclipse was seen only in the following three pictures in order to change the state of the clouds, |

At from 7:36 to 7:38 a.m. in May 21 (Mon.), 2012 (As a thin cumulocirrus covers the sun, choosing the time sunlight becames a little weak, direct zoom lens photography of Annular Eclipse was taken by a digital camera.) It seems that the ghost (which is situated in the right in the each picture) is fairly accurate copy of the annular eclipse of the fact. By the way, the image of the each picture remains in a state that was stored in a digital camera, and the size of the screen, brightness, color and so on are not changed at all. The used digital camera is a popular product purchased in 2007 named "Pentax Optio W30" (7.1 Megapixels). |
| If we expand these ghosts and add the simultaneous pictures shown in Fig.2, we can arrange those as in the following. They seem almost as the same as the predicted annular eclipse in the city of Hitachinaka (Part 2) and also as the same as the observation results. |

Around 7:36 a.m. in May 21 (Mon.), 2012 [Notation] Only when setting the digital camera as a zoom lens, clear ghost appeared by the lens or CCD surface reflection accidentally. |
| The scenery of the circumference of eight minutes later of the annular eclipse is indicated in the following. It did not become so dark that I thought. |
