Hi
Guys this was our first sunshine for nearly 3 weeks. It was good to get
out a do some imaging and processing. It is up to a massive 20degs now and
climbing about 2 degrees per week, things are looking up.

Dear
Masatsugu,
I have downloaded the latest CMO, with the article I wrote; it looks good—the
section on Sithonius Lacus is now corrected. This gives us a new project:
to try to examine what might have been happening at Sithonius Lacus when that
observation was made.

Dear
Masatsugu,
I was in at my office--returning home, I checked the draft of that
article; it can be corrected if Tithonius Lacus is changed to Sithonius
Lacus, and then uf the "also" referring to Saheki's observation is
deleted. Thus the sentence should read: … an intense point of light
suddenly appear near Sithonius Lacus; it scintillated like a star and
disappeared after five minutes; a similar observation, at Tithonius Lacus, was
reported by Tsuneo Saheki on Dec. 8, 1951," etc., etc.
Perhaps Reiichi Konnai would be so kind as to investigate and write something
about Sithonius Lacus--is this also an area of plagioclase and calcium-rich
pyroxene, as the other two areas (Edom and Tithonius Lacus) seem to be?
I sent Dale Cruikshank the draft of the article, and he responded with some
interesting reminiscences about the spectral studies of Mars vs. minerals
he and Alan Binder carried out as G. P. Kuiper's grad students in the
1960s. Perhaps this is something to write up in another article.
Best wishes,

Dear
Masatsugu,
It is my mistake--Sithonius Lacus was a site I did not know
about. I think that de Vaucouleurs meant Saheki's observation as he
refers to a 5" disk. The fact he received no response from Saheki
(if he wrote to him indeed) I
cannot explain. Saheki seems to have known French, as he did have Flammarion's
La Planete Mars as we saw during our visit in 2004.
Perhaps
we need to look into what the mineralogy of Sithonius Lacus is now. This
will be a good project for our readers.
Pardon
my short response--I am temporarily rather disabled from surgery on my
foot.

Hi
guys,
Some images taken last wednesday, with the NNTZ LRS. The seeing was
surprisingly good during the first hours. Due to the presence of the easterlies
at ground level and a relatively strong jetstream, it should have been poor...

I though I'd
use a different method for imaging the Moon on this occasion. Attaching my
Lumenera SkyNYX 2-0 camera (now superseded on C-14 for planetary duties) to an
80mm f7.5 ED refractor at prime focus, I videoed the gibbous Moon at 66fps in
four sections through a deep red filter (Baader "30nm H alpha"),
stacked the videos, enlarging them in the process using 1.5x drizzle in
Autostakkert, sharpened them slightly in Registax, and combined the mosaic on
the Mac using the very reasonable PanoEdit software (10 quid).
So here's a
mono 16-day old Moon. Best viewed full size.

Hi Bill, thanks very much for your Mars essay--I read it with both nostalgia
and close interest, and the limonite issue brought back memories of some work
that Al Binder and I did while we were grad students in Kuiper's lab in the
1960s. I'll attach the two papers we wrote about our measurements of
red-stained rocks in the Sonoran desert in which Tucson is embedded, and
comparisons with our measurements of the near-infrared reflectivity of
Mars. As we point out limonite is only one of several iron-oxide
minerals, and indeed the Mars surface seems to have a number of these, as well
as some others.
I'm sitting in
a Pluto mission meeting in Boulder just now, listening to details of the
spacecraft performance and planning exercises for the flyby in July 2015.

I had a
lateish clearance and could not get the images until a couple of hours after
culmination. Seeing was very variable, with videos taken back-to-back having
very different quality levels.
The sequence taken was RGBI,RGBI,RGBI, all
1-minute videos. The RGB image shows the colours more truly, but the L(I)RGB
shows sharper detail.

Dear
Masatsugu,
Here’s another essay. It may be too long, in which case you can cut it in
half like an earthworm and it may even grow two heads.
I will send it to Christophe and Reiichi as well.
Sorry to hear of your continuing health problems. I am having a few procedures
done here too; tomorrow I have pins put in two toes I damaged cross-country
skiing with bad equipment two years ago, and have decided on the ablation
surgery for A-fib which will be performed in February. I am trying to get
well in advance of my May trip to Flagstaff, where I hope to do some climbing
of cinder cones, meteor craters, and the San Francisco Peaks.

Hi
there everyone - did anyone image this AR ?
Jan 15th Active Region 1654 - PST
40 h alpha Sketch / 8 mm eyepiece / 50 X - up scaled by eye. 10:42 UT - 11:28
UT Pastel , Conte on Black Paper This region was very complex indeed. My first
view of it was yesterday morning. OH boy how to sketch it. ? I tried the
binoviewers but they gave too much information to my eyes for the time I had
available. So I went back to the 8mm set up and settled down for a
sketch. The sun had some interference from chimneys from time to time but the
view was awesome. Indeed the limb of the sun was full of proms of all sizes
while filaments wriggled over the surface like snakes on sand. There were no
bright bursts from the active region as I sketched. Long areas of plage were
flanked by some leaping dark rope like filaments these were flanked closely in
parts by fibrils. The entire AR was solar eye candy. The sun and its massive
action was then masked by high cirrus clouds so no chance of a white light
sketch.
Best and happy new year

I used here the same setup on the C-14 that I've been using for
imaging Jupiter (as it is easier not to change it): the 3x Barlow and Flea 3.
Seeing was not good. This is through an IR filter.
The crater Atlas is 87km in diameter, which makes the smallest
craterlets in this image, and the width of the fractures on Atlas's floor,
about 1km or less.

I've already sent the Moon and Jupiter with the 100mm

culmination so I imaged later. Seeing was very poor, with lots of

turned out surprisingly not too bad, particularly when the I image is
incorporated – a tribute to Emil Kraaikamp's Autostakkert.
