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


ALERT! URGENT! Comet 29P monitoring requested for Outburst capture (1-3 September)

Location of comet 29P as seen from the SSO scopes at  10:34 pm local time as it transits the meridian. The large rectangel is the field of view of T12, the small rectangle is the field fo view of T17. click to embiggen.

Comet 29P is known for it irregular outbursts. It has recently undergone a series of four outbursts in 13 days, reacing magnitude 13.5 (from magnitude 15.7!).  there was a major outburst on August 27, reacting magnitude 12 from magnitude 14.


Comet 29P recent out bursts (taken from the comet and asteroid FB group)

Richard Miles has called fro observations of 29P for possible new outbursts.

"Observers should be alert for a possible third outburst of 29P between now and 2017 September 03.0"


We now have strong evidence of two cryovolcanoes erupting twice on consecutive rotations (local days) of the nucleus during June 27 to August 27.

Looking at the entire dataset spanning 15 years (1 orbit of the Sun = 1 local year), there have been 130 outbursts detected and timed accurately. Of these there have been 14 instances of pairs of eruptions on consecutive rotations, and 10 instances when the same sources have erupted three times - each separated by one rotation. So that amounts to 45% of all outbursts happened on consecutive rotations from a small number (<10?) of cryovolcanic vents. It is this characteristic that makes it possible to predict some outbursts.

In addition, there have been 30 outbursts (23%) that have triggered a further outburst in their vicinity, i.e. within about 60 degrees longitude of each other.

That leaves only 25 events (19%) which are either isolated ones, or are repeat events from the same source but spaced in time by two or more local days on the nucleus. P.S. There are two other factors - one is that during the early years lots of outbursts were missed - second is that outbursts are missed very early on (and late on) in each apparition as the comet is close to solar conjunction."

Recent images of the comet from the Liverpool and Faulkes telescopes are here.

The comet is in Capricorn, between  iota Capricornii and Theta Capricorii, not far from 29 Cap. The comet is visible from both southern and northern scopes, although the Southern scopes have the best view. The comet transits at around 10:30 pm local time, however the waxing Moon will make observations increasingly difficult. On the 3rd the comet is just 6 degrees form the nearly full Moon. Narrow band observations will be required, R band observations may be best.

ALERT NEO 3122 Florence has a close pass 1 September (UT)

Path of NEO 3122 Florence as seen from SSO from 28 August (click to embiggen).

NEO 3122 Florence makes an historic approach in early September. This will be the closest this asteroid, named after reforming nurse Florence Nightingale has come since 1890.

While not a particularly close approach (September 1, 12:06 UT, 0.047 AU, around 18 Earth Moon distances), this will be the closest a large NEO has come to Earth since the class of objects were first described.

With a diameter of about 4.3 km, Florence ranks fourth in diameter of those NEO's classified as potentially hazardous. It is also the brightest of the Large NEO's, brighter than 3200 Phaeton.

Chart showing the track of 3122 Florence in greater detail, the rectangle is the field of view of T12 (click to embiggen)

The asteroid will range from magnitude 9 up to around magnitude 8.7 then fading down to 10. It is initially only visible from the SSO scopes, but by closest approach it is high in both northern and southern skies passing through Capricornius and Delphinus.

Many instruments will be watching this approach, including the Goldstone radar to try and capture its shhape and possible satellites. Light curve data are requested to compliment these observations.  Being bright it requires only short exposures, previous studies suggest a rotation period of 2.4 hours and an amplitude of 0.2 magnitudes.

There is little parallax dispacement of the asteroid, and is moving at 23.86 "/min at closest approach, so tracking should not be an issue. However, at closest approach the waxing Moon is 36 degrees away, so narrow band imaging, preferably r band, is desirable.

While not spectacular, this will be an historic pass to witness, the next closest approach of Florence is in 2057.

ALERT! URGENT "Tabby's Star" KIC 8462852 dimming again, Photometry required

Location of Tabby's star, other wise known as Boyajian's Star, KIC 8462852and TYC 3162-665-1 as seen from Mayhill, New Mexico. The 12th magnitude star is in Cygnus, approximately between alpha and delta Cygni. The field of view of T05 is indicated, click to embiggen.

Photometry is urgently required for "Tabby's Star", (TYC 3162-665-1, KIC 8462852). Originally identified by by Tabetha Boyajian in the Kepler data it is most intriguing because of larger irregular dips in brightness which could not be explained by exoplanets.

The reasons for this are unclear, and everything from disintegrating cometary clouds and alien megastrucures have been proposed.

Now another significant fall in brightness after the first earlier this year is occuring (see here for magnitude graph).

Observations are urgently required to follow this dimming in multiple wavelengths. Full details of what is required for observations are here . The AAVSO also have magnitude comparison charts to follow the star over this dimming.

The star is in Cygnus approximately between alpha and delta Cygni. It is only observable from Northern Scopes, between astroinomical twilight in the evening to astronomical twilight in the morning.

ALERT! Bright new cometC/2016 01

Comet C/2017 O1, discovered by the ASASSN supernova survey, as seen from the SSO scopes at astronomical twilight. The rectangle is the field of view of T12.

Comet C/2017 is a surprisingly bright comet which was recently discovered by the ASASSN supernova survey. It is currently around magnitude 9.8. It is unclear if the comet is in outburst, or has "switched on" as it crossed the frost line.

While the comet is already bright, observations are requested to follow its development. It is predicted to reach magnitude 7.5 in October.

Currently it is between Cetus and Eridanus, above Eta Eri. It is currently best seen in the SSO scopes, from about 230 am local time to astronomical twilight, from the Northern scopes the observations are limited to just before astronomical twilight. Currently it has no ineteresting encounters.

Over the month the comet evolves into a better viewing position, but by September it is more favourable for the northern scopes, and at maximum it is a northern object.
