New TESS photometer online: Stars551

The old photometer Stars209 unfortunately died, after the cover window was blown off by the wind. Meanwhile a new meter was obtained Stars 551.

Link to the data

I’m working to get the data nicely represented.

The cover window of the photocell disappeared
Rain damaged the photocell, the filter came loose

The data from Stars209 were recorded from February 2019 till December 2020, almost non-stop. The CSV download file can be found here:

TESS Photometer down!

Since January 3th the TESS Photometer stopped sending data. With closer inspection, unfortunately the cover glass had disappeared, leaving the device wide open to the rain and snow. After drying, it did work again for half an hour, but then it went silent again.

So after contacting Madrid University I’ve ordered a new device. Hopefully we can log it as STAR209 so that we can continue the datastream.

Jupiter and Antares

Amazing what a difference if you move south with 20° latitude!! That is what happened travelling to Cairo. Constellations and planets are soo much higher in the sky. Was it not for the severe light pollution (estimation SQM 19), the whole constellation of Scorpius would be visible. The upward light rays to the northeast are part of the ‘famous’ sound-and lightshow of the Pyramids.
