Dr Ian Musgrave  - iTelescope Science Advisor

An avid amateur astronomer, Ian writes the weekly sky updates for ABC Radio Science and is science adviser to iTelescope. When not staring at the sky he is an equally enthusiastic molecular pharmacologist at the University of Adelaide, Australia.

You can follow Ian Musgrave on his Astroblog for daily posts about astronomy, biology and life, the Universe and everything.

"Over at Astroblog I largely guide people to the view of the sky as seen with the unaided eye. But I’m also an iTelescope.Net user, and I’m very honoured to have been invited to highlight some of the interesting objects that can be seen through the iTelescopes.

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


Comet 67P Churyumov-Gerasimenko at Perihelion August 13 - Observations Requested

Comet 67P as seen at Astronomical Twilight in the eastern morning sky from MayHill New Mexico, the comet is passing through Gemini. (click to embiggen).

Comet 67, currently being orbited by the Rosetta spacecraft is coming to perihelion on August the 13th (UT).

Observations from amateur astronomers of the comet during pre-perihelion, perihelion and post-perihelion are requested to compliment the observations made by the spacecraft.


 View of the region around 67P from New Mexico, the rectangle is the field of view of T5 (click to embiggen).

Deep observations of the comet are requested, RBV filtered images would be good to help determine dust production and correlate with Rosetta observations.

Unfortunately comet 67P is very low in the morning sky, and only observable from the northern hemisphere scopes. At Astronomical twilight the comet is only 20 degrees above the horizon, around the limit of travel of many of the scopes.

Also, over the next few days the waning Moon will make imaging this faint visitor difficult (the comet is currently around magnitude 13 and may brighten to magnitude 12).

The comet is in a reasonably crowded field, which may make finding it difficult with shorter exposures.

The comet is near the magnitude 5.1 open cluster M35 on the 8th, and the open cluster Cr89 on the 10th.


ALERT! Close aproach of asteroid 1566 Icarus

 Asteroid 1566 Icarus as seen from Mayhill New Mexico from astronomical twilight from  June 16 to June 23

Asteroid 1566 Icarus will  make a rare close approach to Earth on 15:39 UT 16 June at distance of 0.053 AU. It is brightest between the 17th -19th though. With an estimated diameter of 1 Km it is one of the largest objects to get close to Earth this year.

The asteroid is currently magnitude 14.6, and will brighten to around 13.5. It's distance and slow brightening means there is plenty of time to catch 1566 Icarus.

It is well placed to be visible from the Northern Hemisphere scopes initially, although it will also be visible briefly at astronomical twilight from the SSO scopes when it is brightest.

At magnitude 14.5 -13.5 60 second or shorter exposures may be reasonable, tracking should not be an issue.

Asteroid 1566 Icarus is visible for the rest of the month for northern scopes as it passes from Urda Major to Canes Venatici to Bootes then Virgo.

The asteroid is visible from astronomical twilight until early morning for several weeks.

There is minimal parallax issues with 1566 Icarus, and tracking will work well. The MPC one line ephemeris is

May Highlights: Comets 29P, C/2015 G2, C/2014 Q2, 88P

Last Quarter Moon 11 May, New Moon is 18 May,  First Quarter 26 May and Full Moon 3 June.

Comet 29P as seen from the SSO scopes at 10pm in May. Click to embiggen.

29P/Schwassmann-Wachmann is in outburst. Rising from a magnitude of aroun 15.5 on May 6 to it's current 11.7. The coma is still expanding and further observations are requested. This is not the outburst that Richard Miles predicted, but a later one, possibly from a site he has labelled D. This chart of recent outburst magnitudes may be of interest.

Comets C/2015 G2 MASTER as seen from the SSO scopes at aastronomical twilight in the evening from 17 May on, the large rectangle is the field of view of T12, the small that of T9. Click to embiggen.

C/2015 G2 MASTER leaves the morning skys and is now entering the evening skys, but will not be high enough for observation from the SSO scopes until May 17.It will be first visible in Lepus, then move through Canis Major to Monocerous.

Currently around magnitude 6, the comet should remain at magnitude 6-7 as it enters the SSO scopes field of view.

On the 17th the comet is 37' from the 11 th magnitude galaxy NGC 1744. On the 18th the comet is with T12 distance of thee M7.7 globular cluster M79. On the 22nd it is within T12 range of the M8.6 open cluster  M22. Then on the 28th with, a bit of mosaic building, you can get the M7.8 open cluster M50. the M7.2 open cluster NGC 2335 (and a bunch of smaller clusters), and the M5.9 open cluster NGC 2309 in a nice shot.

Comet 88P Howell is high enough in the sky to be imaged by the Southern iTelescopes before astronomical twilight in the morning. It moves from Pisces to Cetus. Currently magnitude 9, it will brighten up to magnitude further in the coming months but remain a Southern object. It has no notable encounters this month. However it June you may be able to make a mosaic with Uranus.

Comet C/2014 Q2 Lovejoy as seen at astronomical twilight in the evening from New Mexico during May. The comet is currently in Cephus and will move into Ursa Minor. The large rectangle is the field of view of T14. Click to embiggen.

Comet C/2014 Q2 Lovejoy is no longer the spectacle it was. However, it is still a very nice target. It is currently around magnitude 9. 

It is now circumpolar, visible only in the Northern scopes. It is at it's highest shortly after astronomical twilight in the evening, and for around an hour before astronomical twilight in the morning.

The comet is within T14 distance of the mag 8.1 open cluster NGC 118 from May 16-24.

The MPC one line ephemeris is:

ALERT! Comet C/2015 F4 Jacques amongst the Galaxies 

Comet C/2015 F4 Jacques near the galaxies PGC 64456 and PGC 64450 as seen from the Siding Spring Observatory at 2:00 am local time on April 18. The rectangle is the field of view of T9. Click to embiggen. 

Denis Denisenko on comets-ml has alerted us to a challenging but interesting imaging opportunity.

Comet C/2015 F4 Jacques comes within 4' of galaxy IC 4991 (PGC 64450 mag ) and even closer to the smaller and fainter PGC 64456 (mag 14.3) on April 17th at about 16h UT. This translates to 2:00 am on the 18th at the SSO scopes.

The comet is in Saggitarius, and is best imaged from the SSO scopes, the observational window runs from around 1 am on the 18th to astronomical twilight on the 18th at just after 5:00 am.

Currently magnitude 15.7, you will need fairly long exposures to bring out the comet, so not smearing the galaxies will prove a challenge if you are tracking on the comet. There are other galaxies so a bit of composition off the comet may be worthwhile.
