Able to Upload Images to HOYS-CAPS?

Hello! The alert asks that images be uploaded to and that data be uploaded to the AAVSO database.

    I applied for a log-in a couple of days ago, but have not heard back yet. Its Monday evening in England now.

    Have folks been able to upload images to HOYS-CAPS? Best regards.


Dear Mike, 

Dear Mike, 

I have seen you registered at Nov. 2, 2019, 1:48 p.m. on our site. This automatic process sends you a confirmation email to the adress you supplied. Could you please check if that email somehow ended up in your spam folder? If not, then please send me a direct email from the adress you want to use and I can try to set this up for you. I hope this helps.

dimmest measurement so far


My measurement from the night Nov 30th to  Dec 1st are my dimmest so far, so without wanting to sound too excited  I'd say that a closer look might be in order, even tho  the campaign has, as I understand it, technically ended on the 30th of November? Unfortunately the weather is rather bad here in Germany atm.


Thanks, yes I have seen this

Thanks, yes I have seen this in our data as well. Indeed we will keep looking at it for the next few days to see what is happening.
