Goldstone Radar Observations Planning: 2340 Hathor, 2014 SM143, 2014 RQ17, 2014 TV, and 2014 SC324
Top: Goldstone delay-Doppler images of 2014 SC324 obtained on October 25. Resolution is 3.75 m x 1.0 Hz. Range increases down and Doppler frequency increases to the right. Time increases to the right and then toward the bottom. The images span an interval of about 45 minutes and show considerable rotation by this object, which has an irregular and elongated shape. The round-trip time was about 5.5 seconds and the observations were monostatic. Bottom: Goldstone images from October 24. These observations were bistatic: we transmitted with DSS-14 and received with DSS-13 due to the very short round-trip light travel time, which was only 4 seconds. This sequence spans about 20 minutes.
Goldstone delay-Doppler images of 2014 SM143 obtained on October 19. Resolution is 18.75 m x 0.5 Hz. The images suggest a rounded object roughly 200 m in diameter.
This planning page covers Goldstone observations of 2340 Hathor, 2014 SM143, 2014 RQ17, 2014 TV, and 2014 SC324, objects that make close approaches within about one week of each other in October 2014. 2340 Hathor Hathor was discovered by C. T. Kowal at Palomar on October 22, 1976. This was among the smallest asteroids known at that time. In 1976 it approached within 0.01 AU (4 lunar distances), but despite the close encounter, surprisingly little is known about this asteroid. Spectroscopy indicates that it's a very common Sq-type asteroid. Spitzer Space Telescope measurements by Thomas et al. (2010) suggest an extraordinarily high optical albedo of 0.6, which does not seem consistent with the spectral class. The rotation period and diameter are unknown. Although a diameter of 0.3 km has been reported in at least two review papers, there doesn't seem to be a primary reference that actually provides a diameter based on measurements. The absolute magnitude of 20.0 suggests a diameter in the realm of 0.32 km, but if the albedo really is 0.6, then this asteroid could be significantly smaller and possibly only ~170 m in diameter. Three tracks are scheduled at Goldstone to observe Hathor on October 20, 22, and 23. If the diameter is close to 300 m, then the SNRs should yield a detection easily. We don't expect to obtain high-resolution images unless this object is a slow rotator or much larger than expected. Several tracks are scheduled at Arecibo, where the SNRs should be strong enough for imaging. 2014 SM143 2014 SM143 was discovered on 2014 September 17 by Pan-STARRS and it will approach within 0.029 AU on Oct. 20. This object has an absolute magnitude of 20.3, which suggests a diameter in the realm of 280 meters. Otherwise nothing is known about its physical properties. This object should be a strong radar imaging target in the third week of October when we hope to obtain images with resolutions as fine as 1/8 usec. Goldstone observations are scheduled on October 17, 19, 20, and 23. The view periods for 2014 SM143 and Hathor overlap on Oct. 20 and 23. 2014 RQ17 2014 RQ17 was discovered by Pan-STARRS on 2014 Sep. 11, more than a month before the asteroid will approach within 0.031 AU on Oct. 22. This object has an absolute magnitude of 22.3 that suggests a diameter within a factor of two of 110 meters. Lightcurves obtained by Brian Warner indicate a rotation period of 0.52 h and a lightcurve amplitude of about 1 magnitude, which suggests an elongated object. Arecibo detected this object and got a bandwidth of at least 6 Hz, which places a lower bound on the maximum pole-on dimension of 110 meters. During the approach in October, this object should be easy to detect with radar at Goldstone and Arecibo but probably not strong enough for detailed imaging at Goldstone. The view periods for 2014 RQ17 overlap three days already scheduled for Hathor and 2014 SM143, so we plan to add this object to those days. We're expecting SNRs for 2014 RQ17 to be comparable to those for Hathor but much less than those for 2014 SM143. 2014 TV 2014 TV was discovered by Pan-STARRS 1 on October 1. This object has an absolute magnitude of 24.3 and is roughly 45 m in diameter. Nothing else is known about is physical properties. It will approach within 4.5 lunar distances on October 18 and it should be detectable during time previously scheduled for 2014 SM143 on October 17. Update: This object was detected at Arecibo, where a very wide bandwidth was seen. This suggests very rapid rotation. Brian Warner obtained lightcurves that suggest a rotation period of roughly 39 seconds. As such, the SNRs for this object will be low. 2014 SC324 This object will approach within 1.5 lunar distances on Oct. 24 when the SNRs could be strong enough for high resolution imaging. The absolute magnitude of 24.1 suggests a diameter of roughly 50 meters; nothing else is known about this object. The view periods overlap time already scheduled for Hathor on Oct. 22 and 23, and in addition, we have obtained two additional tracks on Oct. 24 and 25. On Oct 22 and 23 the round-trip times are long enough that the observations will be monostatic, but on Oct. 24 and 25 the RTT is so short that the observations have to be bistatic. Consequently, DSS-13 is scheduled on Oct. 24 and 25. Due to their diameters and the proximity of their orbits to Earth's, the Minor Planet Center has classified Hathor and 2014 SM143 as "Potentially Hazardous Asteroids."
