@. . . . . . Dear
Masami-san,
I pray that you, your family and the rest of the OAA Mars Section
have been doing well. I am very excited about the current Mars apparition as the
planet will attain an apparent size not visualized for some time. I am certain
that the OAA Mars Section will follow the apparition thoroughly as it always
has. The CMO web site will be a great resource for all Mars observers during the
current and future apparitions. I wish you all the best of
luck.
I have attached my latest Mars
observation for your records. Surface detail was noted although the
apparent size was small (5.6"). A very bright to extremely bright (8-9/10) cloud
was noted over the Chryse-Eden-Arabia region of Mars while employing Wratten 47
(Violet) and 64 (Blue-green) filters. I will continue to send you my
observations in a timely manner. May all Mars observers have clear and steady
skies during the current apparition.
