Hello Mineo:

I am sorry to report that I have not heard FO-29 since 9 July.
Untilthis time the telemetry data had been looking very good
with normal battery voltage, current and a temperature of 19 deg.

Solar array current outputhas been in excess of 1000 mA.
However, I have noticed that the satellitehas been in eclipses
in recent months and that they have been getting longer with a
current  duration time  of 17 minutes with no sun each orbit.

Have the command stations tried to turn FO-29 on?
As I remember this problem  has happened before several years ago
during times of long eclipses.  However FO-29 is now 23 years old
and I am much more worried about it's condition.

I am hoping FO-29 is just "off line" resting until the eclipse
times end or are shorter. I will be sending you recent telemetry
in afuture email.

Any information you can give me would be most welcome as I am
very worried about the condition of my favorite satellite and
good friend FO-29.

Mineo: Here are 3 recent FO-29 Reports. I hope the COMMAND STATIONS
can still communicate with FO-29. Here are my most recent telemetry
reports from July 8 and 9 up to the lastday FO-29 was transmitting
a signal.

I hope the COMMAND STATIONS can still communicate with FO-29.
There is noinformation anywhere on the condition of FO-29.
If you have any information on the health and condition of FO-29,
please send it to me as soon as possible.  
The telemetry looked very good right up until the bird went silent.

73 for now,

I, JE9PEL received a request for the cooperation on FO-29 from
JARL as follows.

Currently, we are working to understand the situation and collect
information. If you have system status data for Fuji-3 (FO-29),
would you like to provide it?

We are considering measures with everyone who has been involved
in the development of Fuji-3 and so on. We would like to check
the data of the system status around July 9, 2019.

We appreciate your understanding and cooperation from all over
the world. Thank you.

From JARL, Fuji-3 (FO-29) ground station.

Dear Mineo and Ken:

We are absolutely thrilled that Fo-29 is back in operation.
The bird is working completely normal.  The telemetry shows
that all readings are very good and normal.

I am sending you just one of my many sets of data with raw
audio recordingand the decoded data in pdf spreadsheet.

Night time data in eclipse also looks very good with battery,
Voltage of 13.8 V at battery current 509 mA.
Battery temperature 17.3 C.

I have much more telemetry data if you need it.

Congratulations on a wonderful, successful recovery of our
beloved Fuji OSCAR 29.

73 for now,
