[BAA-ebulletin 00884] Comet Section

======================================================================
BAA electronic bulletin
======================================================================

At the AGM later today I retire as Director of the Comet Section, having served since 1990.  Whilst this is a long period, it doesn't quite match the record of Dr A C D Crommelin who was Director from 1897 to 1901 and again from 1907 to 1939.  I am handing over to Nick James, but have agreed to continue as visual co-ordinator.  Do continue to send me your visual observations and visual equivalent electronic observations, ideally in the standard ICQ format. You can easily generate exactly the right format by entering your observations into the COBS database at http://www.cobs.si/

Although there are no bright comets currently visible from the UK, there are a few telescopic objects that should be observable once the moon leaves the sky in a few days time.  Looking further ahead, 2013 US10 (Catalina) is still on track to reach around 5th or 6th magnitude in December and January.  It is currently too close to the Sun for observation, though might be seen in SOHO images in early November.  It emerges from conjunction later in the month, and is initially an early morning object.  It quickly moves north and gets into the evening sky in the New Year.  It should remain within binocular range into March.

All the latest observing information will continue to be placed on my web page at http://www.ast.cam.ac.uk/~jds/ though some items will no longer be updated. The list of currently observable comets will continue as many other groups use this, and it links to the charts and ephemerides available from the Computing Section web page.

Charts-info Astrosite Groningen (October 26, 2015)

Dear comet observers,    We have prepared the following new charts for our homepage:    C/2014 S2 (PANSTARRS):    - two 3.0x4.0 degrees charts for the period 30 October - 12 November 2015    These new charts are now available in the charts section of our  mainpage at: http://www.shopplaza.nl/astro    Reinder Bouma/Edwin van Dijk  ----------------------------------------------------------------------------  ----------------------------------------------------------------------------

[BAA-ebulletin 00883] Asteroid 2015 TB145 - close approach to Earth on October 31st

======================================================================
BAA electronic bulletin
======================================================================
Discovered by Pan-STARRS on 2015 October 10, this Apollo-type object probably measures 300-600 metres across and is in a short-period (3.07 yr) comet-like orbit tilted 40 deg to the ecliptic It is due to reach perihelion 0.29 au from the Sun on 2015 December 11. To date, the object appears to be only asteroidal in nature and will pass within 1.27 lunar-distances of the Earth on October 31 17:01 UT.

Observers in the UK have their best views on the night of Friday, October 30/31 when it will attain 11th magnitude and be located between the Hyades and Orion. Unfortunately, its path remains close to a bright Moon and so a medium-size or larger telescope will be required to see it in the glare of our nearest neighbour in space. The following table lists the periods of visibility, etc. for UK-based observers during the run-up to closest approach.

Date / Time (UT)            Magn. (V)  Motion ("/min) Moon illum. Dist.(deg)
Oct. 27/28 23:00-05:00   15.8-15.6    1.5-1.8       100-99%       29-26
Oct. 28/29 22:00-05:20   15.2-14.9    2.8-3.6        97-96%        20-17
Oct. 29/30 21:45-05:30   14.2-13.7      7-10          92-90%        16-16
Oct. 30/31 21:30-05:30   12.5-11.4     32-96         85-82%        17-13

Due to its relative proximity, observers will need to look up an ephemeris of its positions for a location or observatory near them to avoid parallax effects. A good source is available from the Minor Planet Ephemeris Service at:
http://www.minorplanetcenter.net/iau/MPEph/MPEph.html

Make sure you enter a suitable location by clicking on 'Observatory Code' and choosing from the list then entering the IAU Code in the box provided halfway down the webpage. For England, I suggest using the code '456'.

Radar observations of 2015 TB145 have been scheduled and these, it is hoped, will show the object in unprecedented detail (2-m resolution). An informative article can be found on NASA's Jet Propulsion Laboratory's website at:

[BAA-ebulletin 00882] Spectroscopy Meeting October 10

======================================================================
BAA electronic bulletin
======================================================================

I'm delighted to advise that the presentations at the above meeting have now
all been linked from our webpage at  <http://www.britastro.org/vss/>
http://www.britastro.org/vss/

Many thanks to Olivier Thizy and Gary Poyner for doing this and to Jack
Martin for the photos.

Apologies if some of you receive this notice two or three times but I
thought it worth sending to a wider audience and some of you are probably on
these other lists.

I know the meeting was specifically about variable stars but many aspects of
the presentations  relate to general spectroscopy and so should prove useful
in all areas of the subject.

Big Sunspot Crackles with Flares

Space Weather News for Sept. 29, 2015
http://spaceweather.com

HIGH SOLAR ACTIVITY: Big sunspot AR2422 is crackling with M-class solar flares and it has an unstable magnetic field that harbors energy for even stronger eruptions. NOAA forecasters estimate a 25% chance of powerful X-class solar flares during the next 24 hours.  Visit http://spaceweather.com for more information and updates.
