4th of July Geomagnetic Storm

Space Weather News for July 4-5, 2015
http://spaceweather.com

A solar wind stream hit Earth's magnetic field on July 4th, sparking a moderately strong (G2-class) geomagnetic storm.  High-latitude sky watchers who receive this email before sunrise on July 5th should be alert for auroras. The hours around local midnight are usually the best times to look.  Check http://spaceweather.com for updates.

AURORA ALERTS:  Don't sleep through the auroras.  Get a phone call when geomagnetic storms are underway.  Space weather alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).

[BAA-ebulletin 00863] Venus-Jupiter Conjunction: 2015 June 30

======================================================================
BAA electronic bulletin
======================================================================
A short reminder to look out tonight for the close appulse of the two bright planets Venus and Jupiter in the western sky after sunset. For UK observers the weather looks to be very favourable and perhaps the best time to view the spectacle will be around 22.30 local time when they approach to within about 19' of each other. It should be well worth taking a look at the two planets in the same field of view using a medium-power eyepiece, say x100 - x150 magnification.

Venus will be especially brilliant at magnitude -4.4 visible as a 34% illuminated crescent some 32" across. Jupiter at magnitude -1.8, and also measuring 32" in size, has all four gallilean satellites on display: Ganymede being situated furthest from he planet and Io, Europa and Callisto strung out in a line diametrically opposite.

Tell your friends and family too - the conjunction should be quite a sight!

Planets Converge for Sunset Sky Show

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

SUNSET SKY SHOW: The two brightest planets in the night sky are converging for a spectacular close encounter.  On June 30th, Jupiter and Venus will be just a fraction of a degree apart, forming a pair so bright that you can see them even before nightfall. Check http://spaceweather.com for observing tips and more.

SPA Newsletter 33: Aurora alert

SPA Newsletter 33

22 June 2015

Aurora alert
There is a strong possibility of auroral activity tonight, as several coronal mass ejections are currently hitting the Earth's magnetic field. Activity is now at storm level according to Aurorawatch UK.
=============================================
R Corona Borealis fades again
Recent observations show a significant fade of the variable star R Corona Borealis. As of 13 June it had dropped from a peak brightness of about magnitude 7.5 to around 10. For details go to http://popastro.us5.list-manage.com/track/click?u=c3c026b652ea9c4b1c85afb31&id=009553e807&e=65c669f6a5

The star will be featured in the July issue of Popular Astronomy.

Geomagnetic Storm Warning: June 22-23

Space Weather News for June 22, 2015
http://spaceweather.com

GEOMAGNETIC STORM WARNING: A CME is heading directly for Earth, and it is expected to sweep up one or more lesser CMEs before it reaches our planet on June 22nd.  The combined impact is likely to spark polar geomagnetic storms and high-latitude auroras.   Visit http://spaceweather.com for more information and updates.

AURORA ALERTS:  Don't sleep through the auroras.  Get a phone call when geomagnetic storms are underway.  Space weather alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).

[BAA-ebulletin 00861] Light variations from a black hole!

======================================================================
BAA electronic bulletin
======================================================================
The variable star V404 Cyg has just gone into outburst but there is more to it than that as V404 Cyg is an X-ray nova and a low mass X-ray binary (LMXB) with a black hole component.  It also had outbursts in 1938, 1956, possibly in 1979 and in 1989. It has has been intensively monitored since then including by X-ray satellites.

However, perhaps the most interesting thing about V404 Cyg is that observers, including myself and Nick James using CCD cameras, have reported light changes of almost 2.5 magnitudes in less than 25 minutes!  This was from mag 13.0 to mag 15.0.  Most observers with moderate telescopes should be able to see an object of mag 13 visually and will then see this object disappear as it plunges down to mag 15 or so.  However, there is every chance that V404 Cyg may yet increase in brightness and the rapid fluctuations should become easier to see.  CCD observers should have no difficulty in recording these variations.

It is amazing to realise the light is coming from close to a black hole situated at the centre of this binary system.

Finder charts can be obtained from the AAVSO Variable Star Plotter at http://www.aavso.org/vsp where your specific orientation and field of view can be entered to suit.

I must also mention our friend R CrB which after promising to return to normal brightness of around mag 6, only reached mag 7 and has now plunged to below mag 12 again.  So, if you missed seeing it in your binoculars this time, who knows when it will recover again to become visible in such instruments?

If you do make any observations of either R CrB or V404 Cyg, please report then to the Variable Star Section.
