Llano Del Hato Asteroid Survey, Initial Performance I’ve begun an asteroid survey using a 1-meters Schmidt digital camera at Llano del Hato National Observatory (Merida-Venezuela). The latest survey try started held towards the airplanes of ecliptic. To obtain asteroids i utilized good blink comparator, to help you obtaining ranks an effective PSK-2 within the modality of five and you will step one micrometers. Mostly i’ve put IIa-O plates. The fresh new maximun quantity of things entirely on you to dish, of one hours out-of exposition with sidereal at the rear of, could have been twenty-eight asteroids.
The data help us guess a shipment from velocities out of things doing 19-20 magnitudes. The new positions have been claimed with the MPC. Contained in this work i show preliminary results and you may good comparation with most other surveys over just before. Nolan M. C.* Bottke W. F. Jr. Kolvoord R. A beneficial. Greenberg Roentgen.

I’ve noticed a circular address to the number of 951 Gaspra (roentgen = 6400 m) consisting sometimes out-of strong basalt otherwise regarding disconnected basalt. In the strong basalt situation, while a relative speed out-of 5300 yards/s, a direct effect deposits regolith along the whole surface, in occurrences large enough to make https://datingranking.net/escort-directory/college-station/ craters step 1 km or more in diameter. 阅读更多
