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!

Comet Observations 30th December 2018

38P/ Stephan - Oterma
2018 Dec 30.66 UT; m1= 10.0; Dia= 4.5'; DC= 3/4; 25cm L, f:5 (x39) [Chris Wyatt, Walcha, NSW, Australia]
Moonlight; Low altitude = 18.8°; Coma diffuse, opaque centre, transparent outer coma, enhances slightly in Swan band filter.
Comparison stars checked using Tycho-2 data in Guide 9.0; Method= M; Cat= TK

[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
