Part of the lightcurve of the asteroid 36 Atalante measured.

Posted by & filed under .

Veli-Pekka Hentunen and Markku Nissinen measured 5.2 hours (total of the asteroids 9.93 hours spin) the lightcurve of the asteroid 36 Atalante 16./17.4.2007 at Taurus Hill Observatory. The bright late spring sky made the measurements a bit difficult and there won’t be much weeks left in this observing season here in Finland. Veli-Pekka and Markku used 150 sec. exposures and photometric R -filter for each […]

Posted by & filed under .

Veli-Pekka Hentunen and Markku Nissinen measured the lightcurve of the asteroid 173 Ino in 8.-9.4.2007 at Taurus Hill Observatory. The variation in light intensity was very small, only 0.06 magnitudes. Despite that the lightcurve turned out to be very good. The weather was quite gold, -6 celcius, and clear. Veli-Pekka and Markku used 150 sec. exposures […]

Posted by & filed under , .

The asteroid research continued in THO when the lightcurve of the asteroid 31 Euphrosyne was measured by Veli-Pekka Hentunen and Markku Nissinen  in 30./31.2.2007 They used 120 sec. exposures and photometric filter R for the measurements. The comparison stars were GSC3422-1893 (C1) and GSC3422-1322. The Moon made the measurements a bit difficult, but in spite of that the […]
