here's so much happening in the skies lately that we have been overwhelmed with excellent images, making it tough to choose the best candidate for this slot. As the sun seems to be finally showing some activity it seems appropriate to highlight the recent auroral displays, and this excellent image is one of a series sent in by Denis Buczynski. The image was taken at Portmahomack on 19th February using a Canon 400D with 28mm lens at ISO 800 and at f/2.8 - exposure time 33 seconds.

This image of Uranus and Venus (10 magnitudes brighter than Uranus) in conjunction in Pisces was taken by BAA member Maurice Gavin using a Meade ETX-70 and Lodestar-M. This excellent image shows the difficulty of capturing and effectively displaying objects of significantly different magnitudes in the same field.

Maps of Jupiter and its moons

As Jupiter is now high in the evening sky, you may like to look at some recent maps of the planet which we have posted on the BAA Jupiter Section web site, to illustrate the interesting features and events over this apparition.  Some were compiled by individual observers from their own images; the others were compiled by Marco Vedovato of the JUPOS team from images by many observers.

 

You can see the full picture here:

http://www.britastro.org/jupiter/2011report03.htm

Also, we have posted maps of the Galilean moons, from spacecraft, with the major features labelled.  The best amateur images can now record a few of these features (see our 2011 report  no.2 for superb examples)!  Thanks to Bjorn Jonsson and to the USGS for the base maps.

You can see the maps here:

http://www.britastro.org/jupiter/moonmaps.htm

Jupiter is still high enough for good observations, which the BAA will be happy to receive.  And even naked-eye observers can enjoy the view of the planet in the evening twilight, especially as it will be alongside Venus for several days around March 15.

This narrowband image of the north American nebula was taken by Houston based astronomer Dick Locke Image using a Takahashi FSQ-85 refractor and AP 900 Go To mount. The image comprises 6.25 hours total exposure, consisting of 39*5 Ha frames and 36*5 O3 frames using an SBIG ST-8300m CCD camera and FW8_8300 filter wheel fitted with Astrodon 36mm narrowband filters.The Ha frames compose the red channel, with the O3 frames making the blue and green channels, followed by subjective adjustments in Photoshop CS5.

It's a while since we checked on the progress of comet C/2009 P1 (Garradd). Here is an image of it's close encounter (visually anyway) with Messier 92. The image was taken by BAA member Malcolm Forrow using Telescope 4 at iTelescope's Observatory at Mayhill, New Mexico, 32.9 North, 105.5 West, Elevation 2225 metres. Imaging details are attached to the image.

Comet Garradd close to M92

Over the next few nights comet C/2009 P1 Garradd will pass close by the globular cluster M92, in Hercules, and this will make for an interesting observing opportunity.

 

Comet 2009 P1 Garrad on 31st January 2012 by Martin Mobberley

Stewart Moore, the BAA Deep Sky Section Director writes:

Although not a spectacular comet with a majestic tail, C/2009 P1 (Garradd) has endeared itself to many observers by visiting bright deep sky objects on its journey through the heavens.  In late August 2011 it visited the globular cluster M71 and in early September of the same year it made a close approach to the Coathanger asterism.  Now visible in the morning sky, Garradd continues its friendship with deep sky objects by making a close approach to another globular cluster, this time M92 in Hercules.

On February 3/4 it passes within 0.5 degree west of M92, making an ideal photo opportunity. The coordinates of M92 are RA 17h 17m.1 and Dec +43deg 08min.  M92 has a visual magnitude of 6.5 and a diameter of 14 arcmin.  Details and an ephemeris for the comet, which has a predicted magnitude of 6.5, can be downloaded from the Comet Section web page and are also available in the latest BAA paper circular No. 826 dated 2012 January 18.

With the Moon setting just after 04:00 on Feb. 3, M92 and the comet will be found at an altitude of around 40 degree in the east.  Please send all observations to both the Deep Sky Section and the Comet Section.
