Observations from the 2005 opposition of 1506 Xosa combined with re-analyzed data from the 2001 apparition were used to examine the period of 1506 Xosa. The combined data indicate possible periods of 5.9 h and 6.6 h.

Suggested Revised H Values of Selected Asteroids: Report Number 4
Pages 140-143
Faure, Gerard; Garrett, Lawrence
2009MPBu...36..140F    Download PDF

We report the main results obtained by the “Magnitude Alert Project” (MAP) from 2007 to mid-2009. On 2009 May 31 the MAP Database contained 495 asteroids and 5541 measures. Observations were made of 19 minor planets on at least three oppositions for which visual and CCD measures indicated a significant difference from the predicted value. These discrepancies ranged from 0.2 to 1.7 magnitudes. We suggest a revision of their catalogued H magnitude to permit better predicted magnitudes in the future ephemerides of these objects, notably by the Minor Planet Center.

Photometric Observations of 1998 OR2, 1999 AQ10, and 2008 TC3
Pages 145-147
Betzler, Alberto Silva; Novaes, Alberto Brum
2009MPBu...36..145B    Download PDF

The near-Earth asteroids 1999 AQ10 and 1998 OR2 were observed by the authors between 2009 February and March to determine their basic physical parameters. The absolute magnitudes are, respectively, H = 20.4 ± 0.5 and 16.1 ± 0.2 using G = 0.15. The lightcurve parameters for 1999 AQ10 are P = 2.79 ± 0.02 h, A = 0.205 ± 0.005 mag and, for 1998 OR2, P = 3.198 ± 0.006 h, A = 0.29 ± 0.01 mag. The linear phase coefficient for 1999 AQ10 is ß = 0.034 ± 0.002 mag/deg. For 2008 TC3, we obtain B-V = 0.608 ± 0.002.

The Very Long Sidereal Period of 1807 Slovakia
Pages 149-151
Galad, Adrian; Kornos, Leonard; Husarik, Marek
2009MPBu...36..149G    Download PDF

A long synodic rotation period of about 308 h was found for asteroid 1807 Slovakia in its 2008/2009 apparition based on a combination of data from Modra and the Minor Planet Center (MPC). Asteroid brightness estimates found in the MPC data covering several previous apparitions not only confirmed the synodic period and large amplitude of the lightcurve of ~1.0 mag, but also led to absolute magnitude (H) and sidereal period determinations, those being H = 12.6 ± 0.1 and Psidereal = 311.75 ± 0.09 h. The sense of rotation is retrograde.

2009MPBu...36..164W    Download PDF

We report on our collaborations to obtain photometric data on two asteroids. 198 Ampella, a main-belt object, was observed to check previously reported periods. We found a synodic period of 20.778 ± 0.003 h, which is double that of the most reliable of those previous results. The near-Earth asteroid 2008 SV11 was observed in support of radar observations. We found a period of 32.4 ± 0.1 h. However, the shape of the lightcurve was very unusual and so the period remains in some doubt. Radar observations indicate a strongly bifurcated body.

Observations of the Hungaria asteroid 2577 Litva in 2009 late February to early April show that the asteroid is a binary. The primary period (synodic) is 2.81258 ± 0.00002 h and the orbital period (synodic) is 35.81 ± 0.01 h. The depth of mutual events (occultations and eclipses) indicate a size ratio of Ds/Dp (lower limit) = 0.34 ± 0.02. A secondary period of 5.6842 ± 0.0002 h was also found. This is due either to the rotation of the satellite that is not tidally locked with the orbital period or a third body.

During the course of a study of long period asteroids (f < 1/d) within the Hungaria asteroid population, the lightcurves for seven asteroids were re-examined using updated software and techniques. Several were found to have significantly different periods from those previously reported by two of the authors (Warner and Stephens). The most significant change was 2074 Shoemaker, which was initially reported to have a period of 57 h but now appears to be a binary asteroid with a primary period of 2.5328 ± 0.0004 h and a possible orbital period of 55.52 ± 0.01 h. The other asteroids that were re-examined were 1919 Clemence, 3043 San Diego, 3353 Jarvis, 4142 Dersu-Uzala, (20232) 1997 YK, and (101549) 1998 YY2. The reexamination showed once again the importance of placing data on at least an internal system to achieve accurate night-to-night calibrations.

We report on our collaboration to obtain photometric data on the near-Earth asteroid (143651) 2003 QO104 in support of radar observations. Our initial data indicated a slowly rotating asteroid, which allowed radar observers to change their observing schedule accordingly. After obtaining data from 2009 March through April, we were able to determine a synodic period of 115 ± 1 h and amplitude of 1.60 ± 0.05 mag. There are indications that the asteroid may be in nonprincipal axis rotation, i.e., tumbling.

Lightcurve Photometry Opportunities: 2009 October-December

We present four lists of “targets of opportunity” for the period 2009 October-September. The first list is those asteroids reaching <15m at brightest during the period and have either no or poorly constrained lightcurve parameters. In some cases, the asteroid may not be favorably positioned again for many years, if ever. The goal for these asteroids is to find a well-determined rotation rate. Don’t hesitate to solicit help from other observers at widely spread longitudes should the initial findings show that a single station may not be able to finish the job.
