Disappearing coolant leak?

[Rob175]

I just noticed that the coolant leak by the rear wheel has stopped....... a new issue was discovered...... today I notice more coolant on the ground further forward under the car in towards the middle of the car forward of the engine.
Last night while driving it was getting a bit cool outside but rather than raising the top I just turned up the heat and blower motor, drove home and parked in the garage. The inside of the car is dry and there is no smell of coolant. The reservoir was at a normal level, the heater worked fine (but I can’t recall the last time I used heat since it only a summer car)
So, any more ideas?...... I’ll be taking the car out later today for a drive and I plan on checking underneath in the morning to see IF anymore coolant is under it.
