At 12.30 the ground station recorded this pass. At 13.00 I was on the other side of town and heard a sonic boom. Squinted up in the sun to see two low flying jets at high speed, heading out to sea, leaving white trails on a bright blue sky. We aren't far from a military base, after all. Around 15.00 I head to the tower for some checks: increase buffer mins to 2, ensure ventilation around the AGS, check antenna's position. On the roof this time the puddles have dried up and the sky is clear. Some of the old bricks holding the tarp in place have Arbroath imprinted on them, and I wonder when and where in the town they were made. Just a small cold breeze to remind that it's spring, not summer. Daffodils almost seem luminescent in the strong light. Around 16.00 I'm down at the beach, the tide is high, almost all the way up to the sea wall. There's a dead seal that's lost its head and a solid pink plastic bottle left on the stair pillar like an extra ornate twirl. It looks recently left and goes in the bin, the seal looks like it's been there a while.

Today I visited the antenna on top of the tower after it was installed yesterday (thanks to Ross and Kirsten!). There's a bright enough sun to squint but not enough to warm the body, just flush my face. Or that could be the walk up spiralling stairway and the sudden exposure to wind. The AGS is further down the stairs, in the collections store room, just next to the Victorian telescope that I'm told is rumoured to have be used out here on the tower. Now, the gleaming copper v-dipole antenna is standing firm – just a slight wibble in its arms in the gusting wind. Strapped to the eroding sandstone. A lightning rod is a nearby companion, a much older installation. Strong shadows and pools of water sit on the roof from last night's rain. Fast moving clouds make a repeating rhythm of sensations, like drum beats. One beat sun, one beat rain flecks, beat cloud, beat sun, beat rain etc. The wind buffeting is a constant through the day. The sea is silvery in the distance with a slightly hazy horizon. Looking down to ground level, daffodils smile back. Dots of primrose. Bluebells are on the cusp. Perhaps less distinct waves of their flowering than in the past. The beats quicken. Up here it's just me, but down from the tower it's a busy day, the garden club volunteers have lots of spring jobs to do, the Travelling Gallery bus is visiting, the cafe is packed, and there's more going on than I know about. I shout to Andy (who drives the bus) – he can't hear me over the wind, but I take a photo.

First daytime image from the antenna at Hospitalfield. Weather: Increasingly drizzly and windy from the start of the day. Hoods up. Rain that sounds like it might be hail. Dry ground means big puddles.

Yellow weather warning just starting here. Bright but very very windy from 2 floors up, leaves swirling everywhere, bins falling about
