First Train From Makkasan To Airport

[tommytouch]

Can anyone tell me what time the first train leaves Makkasan station for the airport (weekday), and wether it's the 15 minute express service or the slower 30 minute commuter service?

I've looked on their website but it only seems to show times from the Airport, not in the opposite direction.

Thanks
