SQM-LU-DL (Datalogging light meter) / Solar eclipse 20210408

« Last post by admin on April 09, 2024, 01:13:13 pm »

Attached (must be logged in to view), an image of the data logger plot set to every one minute trigger during the eclipse during totality in the Niagara Ontario Canada region.
Peak darkness of 12.73 mpsas observed.
About 11 minutes dark enough for the meter to read darkness.

My personal observation:
The clouds cleared up just enough to see the total eclipse.
Had to use eclipse glasses before and after totality.
Had to take glasses off during totality.
Caught a nice glimpse of the diamond ring before having to put glasses on again, but the cloud were still a bit thick to see anything with the glasses.

General Discussion / Measurements during April 8, 2024 Eclipse?

« Last post by jbirriel on March 03, 2024, 03:09:24 am »

Is anyone planning on taking measurements of the total solar eclipse along the line of totality?  I'm planning on doing so with two sets of LRGB filtered SQM-DLs set to take data every minute. If interested in a collaboration, please contact me at

SQM reader.

Sorry, I misunderstood. That is not our program. SQM-Reader is written by Knightware.

You can get help/support for that program here: http://www.knightware.biz/index.htm

At the beginning seems to work, I wasnt sure enough. This is my written command.

Are you intending to use UDM (Unihedron Device Manager) or SQM Reader (by Knightware)?

For USB meter, use -SUC

-SUC,x   ;Select USB device where x = communication portname i.e. COM1

Other commands are described in UDM->Help->Command_Line_Information.

Try:
 -LCM,1
to read every 1 minute on the minute

If that does not work, then copy your entire command to a message reply here.

I'm interested in "creating a task" using task scheduler in windows 10 to "open" and "start" the SQM-LU reader  everyday at 6:30pm

There are some instructions here:

Let me know if you need more help.
