While many people are familiar with the larger, more glamorous objects in the night sky that make good iTelescope targets, there are a host of lesser known, interesting objects that are well worth chasing such as fast moving Near Earth Objects, Novae and Comets."  Twitter @ianmusgrave


ALERT! Possible Supernovae in M61, NGC 4080; possible Nova in Aries

Three bright objects 2 possible supernova and one possible nova have just ebb reported.

First is a magnitude 13.6 potential supernova in M61, PSN J12215757+0428185:
Possible Supernova (13.6 mag) in M61

R.A. 12h21m57.57s Decl. +04°28'18.5" (J2000.0) 2014 Oct. 29.8376 UT, 13.6 mag (CCD, unfiltered)

Discovered by Koichi Itagaki, Yamagata, Japan. Discovery image is at

The next is MASTER OT J120451.50+265946.6 – possible supernova (13.9 mag) in NGC 4080 (ATel #6634):

Both these supernova are only visible from the northern scopes, and  very low to the horizon (16 degress at astronomical twilight just before sunrise). So very difficult targets for the iTelescopes.

The possible nova in Aries is much more achivable. and is high for a good chunk of thenigh from both northern and southern scopes.

PNV J03093063+2638031: possible "nova" (11.0 mag) in Aries discovered by Seiji Ueda (Hokkaido, Japan)

ALERT! Observations of Comet C/2014 Q3 Borisov Requested

Path of C/2014 Q3 Borisov as seen from Mayhill New Mexico at astronomical twilight. Click to embiggen.

Comet C/2014 Q3 Borisov is a comet that was thought to get no brighter than magnitude 13. Currently visual observers have been reporting it to be magnitude 10-12, with a visible coma.

There has been a call for observations of 2014 Q3 Borisov. I people would like to keep a watch on the evolution of this comet, and pass the results on to comets-ml, comet-obs or the Comet Observation Database.

The comet is only visible form the northen iTelescopes, best in the early morning being highest just before astronomical twilight.

October Highlights: C/2013 A1, C/2014 E2, C/2012 K1 and C/2013 V5

First Quarter is 1 October, Full Moon 8 October (and Lunar Eclipse), Last Quarter 16 October, New Moon is 24 October and First Quarter again at 31 October.

C/2013 A1 (Siding Spring) is dealt with in detail here.

C/2014 E2 (Jacques) continues to put on a nice  display while continuing to fade. The comet is now around magnitude 11. The ion tail is gone but there is still a nice well developed coma.

The comet is now well visible from the northern and SSO scopes as it passes through Aquila, although still best from the northern scopes, where it can be imaged for most of the night. C/2014E2 has only a couple of nice encounters this month.

The comet passes 9' from the open cluster NGC 6756 (mag 11) on October 15. Then on October 28-30 the comet is less than 45' from the globular cluster NGC 6760 (Mag 9)

The MPC one line ephemeris is

Comet C/2012 K1 PanSTARRS from SSO during October. The large rectangle is the field of view of T12. Click to embiggen and print.

Comet C/2012 K1 PanSTARRS is now high enough in  the southern morning skies to image. It currently is showing a great double tail. Currently magnitude 6.9, it is brightening slowly towards a predicted maximum of around 6 late this month.

The comet passes through Puppis, coming close to a number of nice clusters.

On October 14-15 the comet is one degree from NGC 2482 a mag 7.3 open cluster. On the 16th it passes 10' from the open cluster Tr9 (mag 8.2).

On the 17th it is within T12 distance of a number of open clusters, including NGC  2483 (mag 7.6) and NGC 2453 (mag 8.3). On the 21st the comet is within 2 degrees of Cr 132 and Cr 140 (Magnitude 3.5).

On the 23rd the comet is at the edge of Cr 139. This will be a difficult shot as the open cluster is very bright (magnitude 2.1) and care is needed to make sure the stars don't over expose while imaging the fainter comet.

Comet C/2013 V5 (Oukaimeden) has emerged from the evening twilight and is now accessible to the SSO scopes. However, it is a race between the rising comet and the rising twilight. By around mid October the comet will once again be too low for the SSO scopes at astronomical twilight.

The comet is currently around magnitude 7 in Hydrus, heading for Libra and Saturn.

On October 1 it is 39' from the globular cluster NGC 5694 (mag 10.2). On October 11 it is 9' from the globular cluster NGC 5897 (magnitude 8.4).

The MPC one line ephemeris is:

C/2012 X1 LINEAR is around magnitude 12, and fading slowly. Visible in the evening to early morning sky for the SSO scopes, it moves through Indus with no interesting encounters. 

CK12X010  2014 02 21.6239  1.598693  0.989755  132.0988  113.1459   44.3660  20141209   8.0  4.0      C/2012 X1 (LINEAR)

On October 4 39 Laetita is 0.5 degrees from the NGC6455, and on October 5 Ceres  is 0.4 degrees from Saturn.


Comet C/2013 A1 Siding Spring Meets With Mars (19 October 2014)

Binocular scale image showing the path of comet C/2013 A1 Siding Spring and Mars during October.  Click to embiggen and print.

The pair are at their closest on October 19, when at 18:51 UT they will be a mere 1' 51" apart. Unfortunately, this will only effectively be seen from Africa. From the SSO scopes the closest the pair get is 18' 38" before the limit of western travel is reached.

Unless you have been living in a cave this past year you will know this October is the month that comet Siding Spring comes close to Mars.


Simulated view in Celestia of Siding Spring passing Mars. Although the tail appears to pass beteen Mars and Phobos this is a rendering artifact. The comet is well beyond Demios (the dot near the centre).

Passing 138,800 Km from Mars, comet Siding SPring comfortably misses the red planet. For comparison. Mars's outermost Moon Demios circles the planet at around 20.000 km from Mar's surface (on the other had, the average Earth-Moon distance is 384,400 Km). 

A small flotilla of spacecraft are getting ready to either observe or avoid the comet. While the comet itself will miss Mars, the planet may be enveloped in its coma, and there is the possibility that cometary dust and debris will damage the spacecraft. Nonetheless, we are preparing for a bonanza of space based observations.

As well as all these spacecraft, amateurs and professional alike are eagerly watching the comet. in the lead-up to the encounter, and will be watching the encounter itself and its aftermath.

The comet would be interesting in its own right being relatively bright (around magnitude 9) and passing through some stunning astronomical territory.

Indeed, this very plethora of celestial gorgeousness can be a problem, the rich stellar backgrounds make seeing the comets tail somewhat difficult.

You may need to do a MEDIAN combine when stacking images to bring the tail out at its best (messes up the pretties but you can do a separate image emphasising the clusters and so on).

As well as the standard Luminance exposures, if you can take some RBV images that would help the science missions as well (allowing definition of dust to gas ratios etc).

The biggest challenge will be getting images of Mars and Siding spring in the same frame.

With the comet around magnitude 9, and Mars at magnitude 0.9 the difference is enormous. As well, the CCD's on the iTelescopes are highly sensitive. To take an image of Saturn on T27, ype de Lang used an exposure of 0.009 sec (!!!). Other approaches are to use a shorter exposure combined with an extreme filter like a hydrogen filter. Even then Mars will be tiny in all the iTelescopes!

Mars imaged for 1 second using the Ha filter on T9.

Whichever approach you use, you can't get the comet without over-exposing the planet, so you will have to assemble images from separate exposures (ie maybe shoot 10x60 second exposures for the comet and say 2-3 0.009 second exposures of the planet). Obviously some practise will be required to the the exposure parameters right before the night of the actual encounter. 

Outside of the big day there are several nice encounters with clusters and such.

On October 3 the comet is around one degree from the open clusters  NGC 6400 (Mag 8.8) and Cr 338 (Mag 8.0). Outside of T12 a mosaic may be the best way to approach this.

On October 4-6 the comet is within T12 distance of the large and beautiful open cluster Ptolemy's cluster (and a number of smaller ancillary ones). This is best taken as a T12 mosaic with come judicious exposure juggling.

On the 8-9th the comet is within 30' of the Butterfly Cluster M6 (it actually crosses the cluster, but this won't be seen from the SSO scopes) and NGC 6416. However, the Full Moon will be a problem (except early on the 8th, during the total Lunar Eclipse :-)

On the 11-13th the comet is within T12 distance of the open clusters Tom Thumb Cluster (Mag 8.2), Cr 347 (mag 8.8) and Cr 351 (Magnitude 9.3). The comet is fading so longer exposures or more stacking shots will be needed to bring out the comet, but will also bring out the background stars, obscuring the comet tail.

Large mutipanel mosaics with T12 will bring in the Triffid and Lagoon nebulas, however, the shortening length of time before the comet goes below the travel of the itelescopes limits these kinds of mosaics.

On the 21st the comet will be within 19' of the globular cluster NGC 6401 (Mag 7.4).
