Hi, Jim (and
Masatsugu),
I
checked an ephemeris program. For the declination of the Sun and the earth to
coincide (at values near zero), you need to be very near the date of opposition
(May 20/21), and at that time Edom Promontorum will be near the CM only
for observers in the Eastern hemisphere. We'll be out of
luck from
But
Jim--this means that attempts to observe the "glint" phenomenon
won't be a factor in planning dates for a visit to
Best wishes,
Bill

Hi Guys we have had a
lot of autumnal clouds, northerly winds and poor seeing ( no change there then)!
As so very often it was clear on the full moon, when I had a bash at the
Eclipse with my Nikon D7200 and a fairly cheap Nikon 55-300 zoom. Tripod
mounted, bit of East to West drift on 2 secs, but a nice record.
Solar resolution has
been poor with the sun at an elevation of only 27 degrees at best from here. Ha
not too bad at half the mag of the white light. Nice prom though. Note the
massive Ha disturbance round the insignificant AR 2437 and 2435 spots.
Best wishes

An IR capture of Mars

Dear Friends and
Colleagues,
Yesterday, Cassini
executed its 20th close flyby of the small icy moon, Enceladus, in what was the
first of our last three visits to this fantastic world. The close approach
altitude was 1,838 kilometers (1,142 miles) over the moon's high northern
atitudes. Our cameras were active during most of this encounter, allowing the
imaging team and other remote-sensing instrument teams to observe the
Saturn-opposing side of Enceladus on the inbound leg of the encounter, and a
narrow, sunlit crescent outbound.
Enceladus fascinates
us because of a sub-surface, global ocean, lying a few 10's of miles beneath
its surface, that is actively venting into space. And though this magnificent
mission, that left Earth 18 years ago today, is not yet over, we are already
looking forward to the time, hopefully not too far in the future, when we can
travel back to Enceladus with the express purpose of answering the question
that burns in all of us: Could there be life under its cracked and cratered
surface?
For now, dwell on
these fabulous images from yesterday's flyby of a moon clear across the solar
system. We have another flyby coming up on October 28, and then our
last in late December.

Hi Guys, The sun is getting low now here at 51 North. Got to make
the most of it before the winter doldrums, when SAD kicks in! To that end here are
a host of golden solar images to brighten your day.
AR2422 approaches the
limb here, and looking very active in Ha.

Hi Guys
Here are a selection
from the last week in September, taken in very variable seeing, There are two
montages showing at a glance the progress of spot groups AR2420, and the beast
AR2422 that has been a joy to image. I had a good run of clear skies but only
fleeting moments of decent seeing. I have also posted some full size images of
the groups.
30th Sep and Oct 1
and 2 to follow.

Hi Guys here are a few images from the second
half of last month. Best seeing was on the 20th. Most of these images have not
had solar the axis tilt “p” added to them, so are presented appearing rotated
anticlockwise by about about 25 degrees when compared to satellite images. Its
more noticeable just now as “p” is just about at its maximum.
Spot group AR2422 looked quite benign on the 23rd, who’d have
thought it would become fire breathing dragon over the nest week !
