145 Adeona asteroid light curve
Third submission to GOSA project. This was marked as a “Important target” with just 25% completed.
| Object ID | 145 Adeona |

22 Kalliope asteroid light curve
Second submission to GOSA project. This was marked as a “Hot target”. There was a close almost-grazing-occultation with the fainter star nearby. Looked like it was going to be very close but I suspect missed in the end.

(201) Penelope light curve
A large main belt asteroid, discovered by Austrian astronomer Johann Palisa in 1879. Thought I’d try the same technique as for an eclipsing binary. One extra step in AstroImageJ to track the asteroid between frames. Didn’t get enough data to determine a period and comparison stars were impossible to find in this particular field so relative flux only.
