Return of the rain bucket?

The rain bucket attached to my weather station died around April last year. Since then, apart from one time when I opened it up to have a look inside, it's never registered a single thing.

Until a few days ago.

While checking some data this morning I noticed that there was rain recorded between around 07:00 and 09:00 and again between around 12:00 and 13:00. Checking that same day for a station near me it does seem that there was precipitation that day. The times appear to be different but, if I recall correctly, that was the day we had some snow so the different times could be down to the snow melting.

I'm not quite sure what to make of this. I'd be surprised to find that snow caused the bucket to spring back to life and given the nature of the problem (in the past the bucket hasn't recorded anything even when I've picked it up and given it a good tilt) I'd be surprised if it was the volume of water that caused it to work.

Something to keep an eye on...
