Scientist report - astronomy

Radiotelescope

We had a clear decrease of the received signal when Jupiter was under
the horizon and the Sun still in the sky. This was therefore the Sun
going out of the main reception lobe. With the position of the Sun at
this time, we roughly determined the size of the main reception lobe :
+/- 140°. This will be confirmed.

As I said in a previous report, the electronics of the Jove Receiver is
a little bit flawed. I realised yesterday that the reception is
sensitive to people walking in the Hab. Fortunately, Jan managed to
solve that problem with pieces of foam padding. The Receiver is now
shock-resistant.

Last thing : I found a very usefull software (Radio-Jupiter Pro Jove
Edition software), with ephemeris for Jupiter and the Sun, main radio
events prediction, etc. Can I instal it on the yellow computer for the
next crews?

Visual telescope

The weather was perfect yesterday : no wind, no cloud. Unfortunately,
Elnaz and I were too tired, so we went to bed, thinking that the
weather would still be nice today. But we were completely wrong : it's
cloudy and windy. No astronomy for tonight. Tomorrow is another day.
