[BAA-ebulletin 00965] Aurora Alert

BAA electronic bulletin

Aurora Alert

A coronal hole has started to impact earth from 06:00UT 21st March 2017.

The field is unstable both positive and negative however the wind speed has increased to over 690kps.

It may only affect Northern Scotland but it could go further if the field swings negative. I have cloud cover on the Moray coast but it has been seen in Dundee. It is showing on cliff cams 1 & 3 http://www.shetland.org/60n/webcams/cliff-cam-3

[BAA-ebulletin 00961] Invitation to the 2nd BAA Workshop on Exoplanet Studies in support of space observatories: 2017 March 02

BAA electronic bulletin

Dear BAA Member,

The second workshop* on amateur observations of exoplanets (including those in support of the Twinkle and ARIEL space missions) will be held on Thursday, March 02 from 11:00-13:30 in Room G21A on the ground floor of Senate House, Malet Street, University College London, WC1E 7HU. BAA members and others interested in exoplanet studies are invited to attend this meeting.

This is an exciting time in astronomy with, for instance, the announcement just yesterday of the remarkable discovery of the first system of 7 Earth-sized planets orbiting another star**. The workshop will start with a series of short talks followed by an hour or so of active discussion to which all are welcome to participate.

Speakers from the professional and amateur community will give talks on progress towards the goal for amateurs to observe relatively bright stars that host one or more exoplanets. A BAA Exoplanet Working Group, set up following the first meeting, will report back to the community and the Twinkle team will present the science case for the amateur campaign and introduce the list of target stars involved. The challenge of precision photometry required to monitor exoplanet transits of their parent star will be discussed along with plans for data analysis, the development of analytical tools, and the potential for collaboration with other organisations including schools via the ORBYTS programme.

On the agenda are 10-minute talks by BAA members, including a progress update by our working group, namely:

Mark Trapnell - Amateur observing programmes and working together
Sam Anahory - Proposed exoplanet group
Mark Salisbury - Some examples of exoplanet transit observations
Richard Miles - Challenges of millimagnitude photometry

It is expected that time will be available during the afternoon for follow-up informal discussion involving active observers and the Twinkle team, as well as a more detailed consideration of project proposals.

A map showing the location of the meeting can be found here:

The nearest underground rail stations are Goodge Street and Russell Square. We also intend to stream the meeting live on YouTube.

If you are planning to attend then please contact the undersigned, or the BAA Office (0207 734 4145, office [at] britastro [dot] org), to confirm.

See you there!

[BAA-ebulletin 00960] Important Notice about the weekend meeting in Chester

BAA electronic Bulletin...

Important Notice about the weekend meeting in Chester

The date of 15th – 17 September was arranged to avoid the Chester Autumn
Meeting Races. However we have just found out that the race meeting has
been changed to the date of our meeting.

As a result we have brought our meeting forward to *8th – 10th September* to
avoid the race weekend. We are sorry for any inconvenience this may cause
but hotels in Chester are *very* expensive and some are already full for
the race weekend.

Full details will be published on the BAA website as soon as we have all
the speakers confirmed.

Hope to see you there

Hazel

LYRA Next Meeting

Dear Members,
Just a quick reminder

Tuesday 14 February 2017, 7.30pm in the Coach House, Parkhill Hotel

Andrew Robertson: "Telescopes – Choice, Use and Maintenance"Andrew is a hugely experienced visual observer who has owned every type of amateur telescope.  As well as his talk, this will be a great opportunity to discuss all our observing questions.

Best Regards

Lee

BAA electronic bulletin
======================================================================
The evening elongation of Venus, 2017
Venus was conspicuous in the evening sky throughout the Festive Season, but although many members look at the planet from time to time, not many observe it seriously. At present the planet is rapidly approaching dichotomy (50% phase). Visual measurements of the phase are of interest in maintaining continuity in our records of the time of apparent dichotomy; sharp unprocessed images adequately exposed to show the true terminator will also be valuable. Apparent dichotomy arrives a few days early at an evening elongation, and will occur in about a week's time. Greatest elongation occurs on January 12, after which Venus will draw in towards the Sun, and inferior conjunction will be reached on March 25.
During the early part of 2017, Venus will be observable upon a dark sky, and therefore we shall have a really good opportunity to look for any sign of the famous 'Ashen Light' (AL) glow from the planet's dark side. Positive and negative observations are requested, and checking for this phenomenon will be worthwhile once the phase has dropped to around 40% or less. Use of an occulting bar to hide the bright crescent is recommended. Well-exposed integrated light or visual waveband filter images will also be useful, but should be made with an infrared blocking filter. This opportunity to observe upon a dark evening sky comes but rarely in the eight year 'cycle' of ten successive elongations of the planet. In 1993, for example, several positive visual records of the AL were made by different BAA observers from February 14 till March 25, but eight years later in 2001 there were no satisfactory sightings. Back in 1953 there were many positive records by experienced observers such as R.M.Baum, M.B.B.Heath, P.A.Moore and C.Tombaugh.
Another useful type of observation will be to try to image the thermal emission from the dark side. Subtle details of the surface topography can be revealed by image enhancement, and generally the higher ground will have a lower albedo, due to the decrease in temperature with altitude. Recent evidence (Sky & Telescope, 2017 February, page 11) strongly suggests that Venus may still be volcanically active, and what are believed to be fresh lava flows over the summit of one large volcano showed enhanced temperatures during the ESA Venus Express mission. Therefore any albedo variations in current images compared with previous ones are of great interest.
For a selection of earlier results it will be worthwhile looking at the comprehensive 1991-98 and 1999-2007 BAA Venus reports posted at the Section's website, which is linked from the BAA homepage.
Please send your results to me regularly: all observers are welcome to contribute, whether new or experienced.
Thank you very much in advance, and a very Happy New Year.
