Along with the monthly crop of new NEO discoveries followed during April, several other interesting objects were also observed:

 

2009 DP2 was added to the NEO Confirmation page as a slow moving (0.36"/min) 19th mag object on April 3rd, unusual in that it had already been given a provisional designation by the Minor Planet Center (MPC) some 6 weeks earlier (the D of DP2 indicating it had been designated in the fourth half-month of the year). The MPC had matched the discovery observations from Feb 17 & 20th by the amateur run Observatoire Chante-Perdrix (50 miles north of Marseilles) with new observations from two stations of the Catalina Sky Survey on March 27 and 28 and realized the orbit was unusual enough to warrant posting on the NEOCP. With further positions on April 4th and 5th it was found to be a Centaur with a period of 17 years and perihelion distance of 3.8 AU with aphelion out as far as the orbit of Saturn at 9.5 AU though currently it can't get closer to Saturn than about 1.6 AU.

 

Another even slower moving NEOCP object, 2009 HH36 also ended up being classified as a Centaur, discovered on April 19th with the 0.9-m telescope of the Steward Observatory on Kitt Peak. A nearby faint field star caused me a few problems when I first observed it on the morning of April 20th. With 2009 HH36 moving at only 0.17"/min it would take an hour to move just 10" and so the star was never far away but by the next night it had moved into clear sky and was much more easily seen.

 

With observations identified back to March 31 and extending to May 5th the orbit is now given with a period of 45 years and perihelion distance of 7 AU. Aphelion at 18.5 AU is at the distance of Uranus, though again it does not get particularly close to Uranus, but can approach Saturn to about 1 AU. It is currently about 9.5 AU from the Sun and due at perihelion in four years time.

 

In the images taken for 2009 HH36 on April 20th, another unusually slow moving object (0.30"/min) was seen nearby at about mag +20 and a check of the MPC's Minor Planet Checker web page did not reveal any previously known minor planet candidates in the vicinity. The next night, when following up 2009 HH36, this other object was searched for and found close to its extrapolated position.

 

I sent off the two nights of observations to the Minor Planet Center, hoping to be assigned discovery credit for a possibly unusual new object, only to find out that it had already been given as a discovery (not surprisingly!) to the Steward Observatory discoverers of 2009 HH36 and had been assigned the designation 2009 HU11. It turned out to be a Jupiter Trojan, fortuitously within just a few arc minutes of the even more distant 2009 HH36 at discovery.

Using FTS I did photometry of Pluto in several filters (for a prospective

ARPS/Schools project) and was one of 3 observatories contributing astrometric

positions which yielded two MP Electronic Circulars announcing orbits of the

two latest NEOs, 2009 JL1 and 2009 JM1. For the last object, it turned out

that Rob MacNaught, using the 0.5-m Schmidt at Siding Spring about 30 SECONDS

before me, imaged and measured the SAME object. It is reassuring to find that

his positions and magnitudes agreed with those I measured. I also checked the

photometry with AstPhot32 and found the object was not varying in brightness

between successive images.

I shall have to get more ARPS members mobilised to do similarly in the near

future. I've got other jobs to do as well as unplanned observing sessions

like this one!

I don't think the non-circular shape shown is real. It would be the result of seeing combined with the relatively small number of frames stacked (330 frames at 2.8 fps.) I should have taken comparison images of nearby stars on the same night, but it clouded over. I did feel however that I was imaging a body which was clearly not a starlike point. Through the eyepiece it gave the impression of a dull, brownish, fuzzy, minute disk shaded off at the edges, a bit like some small planetary nebulae appear, but a different colour. Again, it looked like a dull disk in the way Neptune does at high magnification, but not the blue colour, but brownish.

9. ADDITIONAL COMMENTS

Report submitted to Gilles Regheere and PLANOCCULT only.

Positive not expected here - site inside south 2 sigma zone.

Observation difficult to analyse due to significant noise and small

expected magnitude drop (0.24 mag = drop to 0.8 x combined ADU). Using

Limovie, and several different aperture sizes, there was no drop to the

expected ADU for more than 4 frames (0.16 sec) in the minute centred on

the central expected time, or 8 frames (0.32 sec) in the whole 4 minutes

recording.

 

Best Regards: Andrew Elliott

Date: 2009 May 25

(Rev. Jan 09)

 

The small magnitude drop and

high noise from the Watec 902H made it difficult to analyse. This

needed the whole Limovie 'learning curve' to be re-traversed, and PC

problems to be surmounted!

Report submitted to Gilles Regheere and PLANOCCULT only.

Site just outside 1 Sigma N track.

Recording scrutinised on high quality monochrome CRT monitor near maximum

monitor. It was not possible to improve visualisation with VirtualDub

and Limovie.

(Rev. Jan 09)

 

The target 2UCAC star (Mv 12.5, Mr 11.8), at 18 elevation, sun

elevation -14, was too faint to be distinguished on the Watec 902H.

So I had to make a quick change to the Watec 120N, which I have not

used much for occultations yet. Although the star was visible on the

CRT monitor, I should have used a longer integration time and Hi gamma.

 

Photometry

 

Roger Dymock

 

Asteroid (01909) was imaged as part of the Magnitude Alert Program. Its absolute magnitude was determined to be 12.9 showing that the current values of 12.3 (MPC, JPL) and 12.6 (AstDys) are in error.

Absolute magnitude was determined using the H/G utility in Canopus and the period of 148.6 +/- 0.2 hrs was also determined using Canopus. The data was analysed by Petr Pravec who confirmed that the period was 148.8.

Lightcurves of two objects observed today with the

Faulkes Telescope North (FTN) and reduced using AstPhot32 and Sloan-r'

comparison stars. Both objects are unusual:

 

2009 HC82 is a very rare case of an asteroid in a retrograde orbit rather

akin to a dead comet. With an absolute magnitude, H=16.2, it is rather

similar in size to a Jupiter-family comet at about 2-4 km across. A stacked

image (attached) in subarcsecond seeing shows no evidence of a coma. From

the lightcurve, it appears to be a slow rotator.

 

2009 JG2 has just been announced this afternoon in MPEC 2009-J51.

Fortunately, today's astrometry has been linked to other observations made

about two weeks ago, and these indicate an MOID (minimum orbital

intersection distance) of 0.00013 AU and so this puts it in the "virtual

impactor" category. It too is a relatively slow rotator with P > 5 hr. It

is currently approaching the Earth reaching 17th magnitude and will be

closest on May 19/20 at 0.030 AU after which time it will be at too low a

solar elongation to be readily observable. With an absolute magnitude of H

= 22.6, it is about 150 meters across.

 

36 images were taken with the FTN of these two objects and 36 astrometric

observations have been reported to the Minor Planet Center.

 

If, as a section member, you would like to participate in physical

observations of this kind, please let me know. Thanks.

A note reporting photometry of 2009 HU44 [a=0.83,e=0.64,i=6.6,H=22.7]

from Faulkes South (E10) images taken yesterday.

 

This object does not appear to be a fast rotator, which is not surprising

given its H mag is indicative of a 100-200 meter size object.

The second series has been adjusted in magnitude to equal the first series

(on average) owing to the lack of overlap between fields.
