Goldstone Radar Observations Planning: (5189) 1990 UQ, 2021 AF8, 2013 WA44, and 2021 GK1
(5189) 1990 UQ 1990 UQ was discovered by Rob McNaught at Siding Spring as part of the Anglo-Australian Near-Earth Asteroid Survey. This object has an absolute magnitude of 17.8 and is roughly 0.9 km in diameter. Its rotation period is 6.53 h and its lightcurve amplitude is 1.0 mag (Warner et al.), which probably indicates a highly elongated shape. The spectral class and pole direction are unknown. 1990 UQ will approach within 0.068 au on May 6 when be a relatively strong radar target, with SNRs sufficient for CW, ranging, and coarse-resolution delay-Doppler images. Observations are scheduled at Goldstone between May 1 - 15. Some of the dates overlap times also scheduled for 2013 WA44, which will be a much weaker target. This asteroid will brighten to about 15th magnitude in early May when it will be a very good target for optical observations that could yield its spectral class and perhaps improved constraints on its pole direction. Due to the rotation period and our guess for the diameter, we are expecting a bandwidth of roughly 14 Hz, but it could vary considerably as the asteroid spins due to the elongated shape. 2021 AF8 2021 AF8 was discovered on January 14, 2021 by the Mt. Lemmon Survey. The absolute magnitude is 20.1, which suggests a diameter within a factor of two of 300 meters. Otherwise the physical properties are unknown. 2021 AF8 will approach within 0.022 au (8.6 lunar distances) on May 5 and it should be strong radar imaging target with SNRs sufficient for high-resolution delay-Doppler imaging. Tracks are scheduled at Goldstone on May 1 and 3 and at Canberra on May 5 and 6. 2013 WA44 2013 WA44 has an absolute magnitude of 23.6 that suggests a diameter of roughly 70 meters. It was discovered on November 28, 2013 by the Mt. Lemmon Survey. Lightcurves reported by Thirouin et al. (2016) give a rapid rotation period of 0.35 h and a lightcurve amplitude of 0.23 mag, which probably indicates a shape with a low elongation. The spectral class is unknown. This object will make a relatively distant flyby within 0.062 lunar distances on May 17, when it will be a weak radar target that we may struggle to detect. 2013 WA44 has a relatively low delta-V orbit and is a possible target for NASA's Near-Earth Asteroid Scout mission. 2021 GK1 2021 GK1 was discovered by Pan-STARRS 1 on 2021 April 3. This object will approach within 0.0038 au (1.5 lunar distances) on May 11 when it will be a strong radar target. We hope to observe this object on May 1 or 2 during time already scheduled for 1990 UQ. If successful, we may also try observations on May 10 and 11 when the SNRs will be much stronger. The absolute magnitude of 27.1 implies a diameter within a factor of two of 14 meters. Otherwise nothing is known about the physical properties of this object. This object is on the NHATS list of spacecraft-accesssible targets.

Echo power spectrum obtained on 2021 May 7. Resolution = 0.1 Hz. The figure shows a weighted sum of data acquired over 42 minutes, corresponding to about 38 degrees of rotation. Delay-Doppler radar images of 1990 UQ obtained on May 7 at Goldstone. Resolution is 75 m x 0.3 Hz. In each panel, range increases down and Doppler frequency increases to the right, so the illumination comes from the top and rotation is counterclockwise. In the collage, time increases from the top left to the right and then down,so the last frame in the sequence is at the lower right. Each image is an integration spanning about ten degrees of rotation. The entire sequence lasts about 45 minutes.

Setups
1990 UQ: We're expecting a bandwidth of about 14 Hz. 2021 AF8: The rotation period is unknown. We're expecting a bandwidth of less than 15 Hz. 2013 WA44: This object is a rapid rotator with P = 0.35 h. We're expecting a bandwidth of about 20 Hz. 2021 GK1: We don't know what to expect for the bandwidth. Many objects in this size range rotate rapidly, which would correspond to a large bandwidth.
