is interested in the history of solar astronomy I have completed an article for
the forthcoming issue of Solar Observer [online] magazine but I have tried to
trace all the primary sources where this is possible. Here is access to a

taken months to put together and remains a dynamic document as more of these

Hello Bill!
Good to hear from you, glad that you had a relaxing time on Mars Hill and that,
hopefully, you will be able to renegotiate your hospital position as a less
stressful one.
Yes, I saw Kevin a few weeks ago at Chabot - unfortunately he was running late
(he misjudged the impossible Friday afternoon East Bay traffic), but when I
described to him what I'd presented, he said he'd be happy to host me at Lowell
for the same or a similar presentation on observing and exploring Mars - but I
will probably wait until new versions of my book are released.
@@My work is done at SFSU - for now. Grades turned in this week and I
don't have to go back to teaching until spring semester. I'm waiting to move
into my new office at home - renovating my son's former "lair"
downstairs where I can have a private, quiet place to work, and looking forward
to it. Haven't decided what to work on next, book-wise, as I'm deep into
discussions with my publisher over the new editions of Venus on Mars - print
and ebook editions will be released late this fall, and more complicated
multimedia iBook edition and fine art limited edition should be out soon after
the first of the year.
@@I'm actually producing an album to go with the multimedia edition - will
feature my husband Phill's music/sound compositions, so we're sorting out
tracks and sound elements for each. Each track will have some thematic
connection to the narrative, like "afterlife" (for Letha), "the
big bang," and of course "dust storm on Mars."
@@Also talked to my publisher yesterday about what kind of "art
object" will be a part of the fine art limited edition - I know you had
suggested the globe-maker you know who has created Mars globes in the past - I
suggested this and she is definitely interested - she'd like to talk to the
globe maker, if possible, about possible ways to customize a Mars globe. So is
there any way you can contact the globe maker and see if he's interested, and,
if so, if he'd be willing to have a conversation with my publisher - if so,
then many thanks! We are also thinking about possibly creating a planetary
mobile, maybe with a tiny model of Mariner circling Mars. Do you think your
friend would be able to do something like this?
@@One of the things I intend to do over the next week or so is gather all
the notes I scribbled in the margins as I read your "Passion for the
Planets" manuscript and email them to you, thinking that may be the next
step toward our further discussing a collaborative book project. I'm sure this
will have to wait until you complete your Galaxies project. Sounds like that is
going well. I remember reading in Marcia Bartusiak's book that the reason
Hubble got the recognition more than Slipher (about the expanding universe) is
because of his ego and the fact that he promoted himself relentlessly - and I
guess his position at Mount WIlson was a great help for him doing this.
@@I'm heading to LA in a few weeks and am thinking of visiting Mount
Wilson, which I've never seen - do you know someone there I might contact to
who might be able to show me around? Of course I'll go to Griffith as well -
it's always a pleasure.
@@Hope your summer goes well, with work, with writing, with everything.
More soon.

Hi guys I am sending out two batches of images from
this date as there are 12 images all together. I think the 82Gb of avi data is
a personal record from one session. There was a flare in progress during
imaging of ar 1756. I did an animation from 10:02ut to 10:38ut. You can also
see the flare in the mosaic shot timed at 10:00ut.
I imaged the large prominence at 08:42ut and 09:13ut
both are here. One shot is shown rotated -90 degrees. I finished off the session
with a few spot group shots off the wedge, using a Baader solar continuum
filter and an IR blocker plus of course plenty of ND filtration.
The filament shot was taken using a double stack
solarmax scope.

Saturn + dark spot, May 28
Received;
29 May 2013 at 22:04 JST
Hi all
,
Seeing last night was a little better than I've had recently, I grabbed lots of
data in several channels hoping to capture the dark spot in the NTB/NTZ. in the
end it was visible only in the red channel, and not in the green or either IR
(742nm or 807nm). This is likely due to the nature of the seeing as much as the
intrinsic brightness of the feature.
With
enough massaging (and a little bit over-processed as a result), and merging
multiple data sets in WinJupos I ended up with this quite interesting image.
The dark spot is clearly seen to the upper right, just below the lighter zone
created by the 2010/2011 storm. It has a chain of lighter spots left behind it
(to the left as we see it here).
The
polar hexagon is on display, as well as an evenly spaced series of lighter
spots around the mid-north latitude.

Dear

Many
thanks for all the kind words...
You can trust me, I'll do my best to maintain the CMO publication. It's a
particular media among the amateur world and I think it has a good format for
communicating. Moreover, it has now an incredible density of papers !
I'm
quite happy to meet Reiichi and Reiko. Maybe we are going to visit the Paris
observatory, as we did for the IWCMO four years ago. Since last year, I have
begun to taste red wine and now I'm beginning to differentiate them and know
which one I appreciate most. With moderation as we say in France, it has also a
nice dimension of "culture"...
You
would appreciate Nantes quite a lot. The city is marvellous, and I'm very happy
with my life here. I always discover new things and I'm missing 90% of all
there is to see...

Hi
all,
The long run of poor seeing continues here and across much of Australia. I've
attached an amusing image courtesy of Weather Underground that shows the wind shear
between ground and high altitude (200mb level I think). Orange is bad.
To help counter this I've switched to a longer wavelength IR filter which is
less affected by seeing. It passes 807nm and longer. The image here is a
combination of 3 separate images merged in winjupos. The images were taken
across a span of 6 minutes. There is not very much visible on this side of
Saturn in this filter, poor seeing hides all but the most obvious features.

Yesterday I was privileged to witness a very large

process the data, but have attached a few quick attempts.
I used a Coronado SM40 filter and Flea 3 CCD.

Hi Guys here is an image from the 8th May . I have put
it alongside one from the 1st, as I am, keeping an eye open for any
apparent changes in the globe colour. Back in 2005 we hade some excellent
seeing at opposition and I noted that the globes colours became very
subdued, they just "would not process right" . This
opposition we have had some clear skies and viable seeing for the poor
altitude, so worth a look. I have added images from Feb and March
2005 for info.
Will we ever have seeing like that again I ask ? !
This particular flea colorcam , whilst it creates
an overly red image with a dim blue, It is easy to balance and
correct with consistency, to give a neutral grey ring
set.
