Comet Chasing Group Policies

The primary mission of this group is to promote recreational comet
observing with a emphasis on visual observation.

Observing the fainter telescopic comets at the telescope as if they are
moving deep sky objects is what Comet Chasing is all about.

A note about terminology: "Comet Hunting" is the common term to describe
the act of searching for new comet discoveries. Please use the term "Comet
Chasing" to refer to the observation of known comets to avoid confusion.

(1) Everyone is Welcome

Everyone interested in comets is welcome here, no matter their
level of experience. As this group was specifically created to promote
the hobby, newbies are particularly encouraged to ask questions.
Experienced comet observers are encouraged to answer these questions and
share their experience.

(2) Posting of Observations is Encouraged

The posting observations makes this group an excellent resource for
those who are wondering what they can see in their own telescope. The
observation format is very informal. Visual magnitude and coma diameter
estimates are quite welcome, but not necessary. Please try to avoid
acronyms or abbreviations. E.g. rather than ML write "magnitude limit"
whenever possible. Useful observations should include the following
information:

a. The aperture of your instrument (e.g 7x50 binoculars, 4-inch
telescope, etc.)

b. An idea of your observing conditions. This could be anything from a
naked-eye limiting magnitude to a general idea of how dark your skies
are (e.g. downtown of large city, out in the country with only some
light pollution, etc.)

c. How easily the comet was seen (e.g. Very difficult with averted
vision, big bright and obvious, etc.)

(3) Keep Postings on Topic and of Global Interest

This is a very focused group with members from around the world.
Postings are limited to the topic of comets only. Although the
primary purpose of this group is to promote Comet Chasing, any
discussion related to comets is welcome including comet imaging,
historical comets and comet science.

Specific prohibitions:

a. Ads or promotions for commercial products are not permitted.

b. General announcements of events or meetings that are of local or
regional interest only are not permitted. Announcements of events that
are of specific interest to comet observers *are* permitted.

c. Email attachments are not permitted and are automatically removed.
If you wish to post images or files please upload to the Images or Files
section of the group web site.

(4) Always be Kind, Friendly and Respectful

Postings must at all times be respectful of others. At no time are
personal attacks or arguments of a personal nature acceptable.

(5) Keep Posting Relevant

Please try to keep "me to" type postings to a minimum, and trim all
replies appropriately. Please consider that there are many group
members and avoid filling mailboxes with conversations between only two
parties. Such conversations are often best taken to private email.

(6) Software Tools and the Group Founder

As many of you know I am an astronomical software developer. I did not
create this group to promote my software and will avoid discussion of my
products here. Questions or discussion of my software should be
directed to me personally, or to the SkyTools group:
http://groups.yahoo.com/group/SkyTools/

As the group grows I will solicit co-moderators and in time I hope to
turn over the group to one of them, eventually becoming just another
group member.

Hello everybody,
here are my latest comet observations:


C/2018 V1 (Machholz-Fujikawa-Iwamoto):
2018 Nov. 17.19 UT: m1=[9.4, Dia.=!4.5', 20x80 binoculars, NEGATIVE
[No chance to be seen in such altitudes. Fainter than 9.4 mag.]


46P/Wirtanen:
2018 Dec. 22.80 UT: m1=4.4:, Dia.=&30', DC=0/, 20x80 binoculars
[Observed between clouds and after almost the whole afternoon of rain. Observation was also influenced by strong moonlight. Due to these reasons are the magnitude and coma values uncertain.]


ICQ formats are available on COBS.


Nice day and happy New Year to everyone!

[BAA-ebulletin 01023] EPWS 2018 Survey on women scientists in Europe

BAA electronic bulletin

Female members of the Association may like to complete this survey as
requested below. And please feel free to circulate widely too.

Best regards,

Callum

Callum Potter
President
British Astronomical Association

======================

Dear Colleagues,

The European Platform of Women Scientists EPWS has launched a general
survey on women scientists at the European level and we are kindly
requesting your cooperation in its dissemination. As you know, EPWS is
representing the needs and concerns of women scientists in Europe and
we wish to know what they are in 2018.

The aims of this initiative are to:
- collect the current needs of women scientists - at all career levels;
- evaluate the professional networks of women scientists and know
their expectations regarding these networks;
- assist EPWS defining appropriate actions to be taken and policies to support;
- help women researchers improving their working conditions and
developing their careers.

This survey is intended for women scientists working in research
institutions or in academia, public or private, members of an EPWS
network or not.

It is designed in accordance with the European directive GRPD relative
of the personal data. The results will be collected anonymously as
well for the person answering as for the institution to which she
belongs.

EPWS is requesting your participation in the survey dissemination:

- sending the link to all your individual members,
- asking them in turn to distribute the survey to the women
researchers of their own institutions.

It is essential to collect the maximum possible number of answers by
country for the survey to be valid.

The survey will be available until December 31st, 2018, at the link:
https://epws.org/general-survey-on-women-scientists-2018/

I count on your active collaboration for this important action and
thank you very much in advance for disseminating the survey and
answering it yourself at reception of this message.

Claudine Hermann

EPWS President
