VPHOT continues to be down

VPHOT has been down since yesterday. Is there someone working to resolve this? I have 3 observations piled up waiting for this application to be functional. Is there a better place to report this? No ‘Help’ or ‘Support’ link anywhere on the Website.

I just tried it (10pm EDT) and it seems to be up again, but I see no images in my image list. I uploaded some just over a month ago and I don’t think it deletes old images that soon, does it? (I know that at first it only shows you recent images but I expanded the filter options to show everything and still see nothing.)

Hi,

we are receiving a lot of images and the grace period for the images has been lowered to 12 days, so images uploaded one month ago has been deleted.

We had a couple of failure because the space on the server was completely filled so we had to take this decision and possibly this limit will be further lowered.

Please remember that Vphot is not a storage system, upload images, do the analysis and delete them so everyone can take advantage of the system without issues.

I understand lowerig the time limot. But when you do, pleaseannounce it LOUDLY, like put it on the home page banner.

BTW: Still down. Allowed me to stack, but not analyze a time series.

I agree with you but with the server with no disk space available lowering the retention period for images was the only option.

Hello everyone!

I have images from two telescopes: the BSM_NM and the DSO35. The strange thing is that I was able to stack the images received from the BSM_NM and take photometry, but I can’t stack them and take photometry from the DSO35.

I have the same problem. I think it has to do with the size of the images. From DSO35 the images are 40 Mb. I have other images that are 8 Mb and they can be processed without problem.

Hello everyone!

Just to let you know I am affraid VPhot is still not working correctly. I have not been able to run a Time Series with data uploaded from AAVSOnet.

Stacking is not an issue, and I see all my images.

Cheers!

I’m having repeated problems with VPHOT as well. Its a terrific application when it can be accessed, but sadly, it seems to have problems more and more often. Its getting to the point where a shift to AIJ or Peranso is required. I wish our membership fees and donations could be more-focused in maintaining or creating the tools that make our volunteer time, observations and reports more of a convenience rather than a frustration.

Hey again,

My bad (again). VPhot is running great right now. The impossibility to generate a Time Series report was due to the fact that I had too many cookies stored in my browser. I erased them, and everything is working well now.

Cheers,

I guess a lot of people are seeing the same thing right now but thought I’d post it anyway in case it is of any use. I have some images from DSO35 in my list right now and cannot open any of them; each time I get the out of memory error shown below. I get the same thing if I try to stack them. Downloading also fails with a “server connection failed” error.

Gary,

I think you mean Phoranso (Photometric Reduction and Analysis Software).

Just wanted to second I’m seeing exactly this message, also from dso35.

I just tried it again this morning and VPhot is letting me load the images from DSO35, and letting me stack them (though I am only stacking two images).

Brian (SBQ)

Hi all,

actually the huge images from DSO35 have made life a bit harder for Vphot memory management.

We are trying to fine tune the memory management, last Friday we made a change that should improve the situation.

If you had issues since Saturday please post in the Vphot forum specifying the operation you were doing and the number and size of the images involved.

Thanks

I’m sorry, I think I broke VPHOT. I had 10 images from DSO35 that I tried to stack and got the OutOfMemory-error. Yesterday I tried to stack them 2 and 2 and then stack the 2s 2 and 2, it worked. Today I tried to stack all 10, it didn’t work.

The huge images from DSO35 has an area of about 1 deg 20 arcmin. I only need the 30-40 arcmin in the centre. Could there be a process that cut out the centre to reduce the sizes of these images? Or maybe use bin 2x2?

I have been receiving images of the same field (NGC 7790) from two systems. DSO35 and NH2. I noticed this evening that the images from NH2 worked in VPhot (can load, stack, apply transform), but when I switched to DSO35 images they didn’t work (the system memory problem). In the recent few weeks I also noticed that DSO35 was most likely to be unavailable, much more than other systems, BSM-S, or BSm-Berry, or NH2. (Too bad, since DS035 gives very good images.)

I mention this only in case this can give more information about what is happeneing.

Hi,

images from DSO35 are bigger so a lot of memory is required and stacking 10 of them right now is going to trigger the OutOfMemory error.

We are investigating if there are possble optimizations to apply to overcome this limit.

In the meantime cropping the section of the image you are interested in could be a good workaround.

Astropy has a good library for manipulating fits file, or maybe you can use some desktop software as DS9.

VPhot with DS035 images has been working normally all day, or at least whenever wanted to use it. Whatever you may have done to the system seems to have worked. The analysis tools and transforms also functioned normally.

Usually I stack four V’s, four I’s, and eight B’s for my current target. Basted on what you just wrote I’ll switch to stacking four B’s.

Also I’ll play with DS9 to see if I can get it to batch crop the images. Thanks for the hint.

I got new images from DSO35 today and while I can view them individually I can no longer stack even two of them, getting an “out of disk space” error. Download attempts through the UI fail with the same error, and using the ftp link (which sometimes works even if the UI download doesn’t) fails silently, I assume because of the same disk space problem.
