Hi all,
Some good images taken at the minimum value for De at -0,4°.
Dione and its shadow are followed in transit in front of
the globe during the session.

2027: Mars Is For All of Us:
An International Celebration of the
150th anniversary of Mars's Great Opposition of 1877, and All It Brought
William Sheehan
As many of you are likely aware, the
year 2027 will mark 150 years since the great Mars opposition of 1877, at which
Asaph Hall discovered the moons, David Gill observed
the parallax in order to try to determine the length of the astronomical unit
from Ascension Island and--most relevant here--Giovanni Schiaparelli
at the Brera Observatory and Nathaniel Green at
Madeira produced rival maps of Mars. They could hardly have been more different--and this should have
been a cautionary tale, as it suggested that perhaps subjective/stylistic
effects were important in what was reported by different observers at the
eyepiece. In the end, Schiaparelli's schematic map
was far more influential than Green's, and so the canals burst upon the
scene--and with them a preoccupation with the possibility that Mars might be
inhabited that would last for at least thirty years.
There will be an opposition of Mars
(not very favorable) in February 2027, and initially it was proposed by Jean Guerard of the Societe Astronomique de France (Juvisy
Observatory) and Todd Gonzales (Lowell Observatory) that some kind of joint
observing session could be held at these respective observatories for the
opposition. It was then suggested that it be a one-off. However, on getting others involved in the conversation, it was
realized that the canals of Mars and the era of planetary astronomy they represented
was likely to attract wide interest, and so we began as a small group
(including also Sarah Anderson and Paolo Tanga at
Nice Observatory) to explore the possibility of doing a series of events
running from February through September (the anniversary of Mars's 1877
opposition) held at various institutions, with talks, art presentations, wine tastings, as well as observing opportunities with classic
telescopes featured. These meetings would be broadcast by
Zoom or other technology around the world from the locations at which they were
held. Possible topics and participating institutions (with dates and other
logistical details to be determined):
1. Mars in the pre-Schiaparelli
era--Father Secchi, Phillips, Lockyer.
Vatican Observatory, INAF-Osservatorio Astronomico di Roma (Secchi drawings), Royal
Astronomical Society,
2. Asaph Hall discovers Mars satellites,
Gill Determines Mars's Parallax, and Trouvelot first
observes a Mars planet-encircling dust storm-

3. Right- and Left-Hemisphere Views of Mars: Schiaparelli
vs. Green
Brera Observatory,
4. Confirmations: Perrotin and Thollon
Observatoire de Cote d'Azur
5.
Societe Astronomique de France, Juvisy Observatory
6.
Boston-Brahmin, Far Eastern traveler
and writer, and astronomer Percival Lowell establishes an (at first) temporary
expedition to observe Mars in 1894, with a borrowed telescope and borrowed astronomers,
W.H. Pickering of Harvard and Pickering's assistant A.E. Douglass. At the same opposition, E.E. Barnard observes Mars independently,
and with very different results, at Lick Observatory near
Lowell Observatory, Oriental
Astronomical Association (on Lowell's travels in Japan and also on the work
done by later Japanese observers whose interest in Mars was stimulated by him
and Pickering), Royal Astronomical Society of New Zealand (site of the borrowed
18-inch Brashear refractor), Vanderbilt University? (Barnard
archives), Lick Observatory.

Canals.

8. Still Searching for Life
The human fascination with Mars
continues, as spacecraft--orbiters and rovers--continue to investigate the
planet's conditions as a possible (ancient) abode of life.

Hi all,
An R610LP image from this afternoon, produced from 2x60s captures, with winds gusting up to 7m/s.
Syrtis Major can
be made out to the right, and I was a little surprised at the brightness of the
NPR.
With solar elongation of 17 deg, chasing Mars at this stage
has become more of a personal challenge than necessarily adding value!

Hi all, here's an image of Saturn
from last night in reasonable seeing using a 650nm longpass
filter.
A number of faint cloud features can
be seen on the disk. Rhea can be seen to the left of the rings.
8 images spanning 12 minutes were
measured and merged in Winjupos.
