Jupiter Observation

Last Updated 09/30/08

Here is my Jupiter observation data archives. I have been observing Jupiter visually (Drawings and Central Meridian Transit observation - CMT) since 1974. I will open my observations in this HomePage as much as possible (up to the limit of disk space given to me).

Please contact me, when you wish to use these drawings, CMTs, etc. for any pueposes. My mail address is: kuniaki.horikawa@nifty.com

Web Site of Oriental Astronomical Association (OAA) Jupiter-Saturn Section has newly been opened!

Using a part of my site, a new web site of OAA Jupiter-Saturn Section has been opened. In this site, I provide translated version of monthly reports of the Section, which are published in the OAA journal "The Heavens", because we receive many images from foreign observers, and "The Heavens" is published in Japanese only.
