@cthuljew: Laurence is not yet in the live commentary so it's me for the time being. But as far as I'm aware, I have a white-on-red ESPN logo and he has a red-on-white ESPN logo. Different liveries for team-mates - banned by the FIA, not by ESPN.
Track temperature a whopping 3.4 degrees Celsius as we approach 0930.
@Dhruv: The new site is different to ESPNCricInfo and ESPNFC. I've seen it in testing (in Hammersmith, not Jerez or Barcelona) and think it looks very easy to navigate indeed.
@Prithvi: It's certainly very easy to have an educated guess yesterday - usually during a long run it is safe to assume there are higher loads of fuel. But sometimes even shorter runs can be fuelled heavily - yesterday Maldonado set a headline time on soft tyres but said it hadn't been a low fuel run. So it's really a mixed bag and I'm not too keen on wildly speculating.
@SurendranSelvaraj: ESPNF1 ;)
Rosberg will be driving with a big smile on his face today.
Usually we would update a timing screen at this stage but there are only three official times up there. No-one has completed more than 10 laps either.
It's only Ricciardo and Ericsson out there at the moment. The tapping of keyboards in the media centre is the only noise I can here at the moment.
Two consecutive pit-stop practices for Red Bull. On both occasions the Renault sounds a little grunty as it leaves the pit box.
@Dhruv: At the moment Alonso has just three laps to his name. Honda tweeted earlier that it was now time for the proper test to begin so it sounds confident about completing more laps.
I've just watched two more Red Bull pit-stop practices and the first was pretty poor. The second one just now was much more seamless but great watching the mechanics practising that in real time.
@aman: There are still eight hours and 12 minutes of today's test left so I wouldn't fret too much.
@Tungath: Still no change - only three times - one of which is Rosberg, 52 seconds off the pace from an installation lap. So nothing significant to report.
@Rishabh: I think it's still too early to say, but the long runs of Mercedes in Jerez are still the most significant for me.
Massa is really putting some quick laps early on this morning. His last time was a 1:27.772.
I am off for a wander down the paddock. I will leave you in the hands of the very capable hands of pun enthusiast Laurence Edmondson in my absence.
Testing, testing ... Is this thing on?
@Tungath: Nothing major like 2009 that we know of so far. The power units are still a big talking point and no one is quite sure what Honda has under the McLaren engine cover - there's a split turbo but we don't know the reason for the throaty exhaust note. Aero-wise, blown wheel nuts have caught quite a bit of attention with several teams - inlcuidng Red Bull, McLaren, Ferrari but not Mercedes and Williams - adopting the idea. Basically it takes air from the brake duct and spews it out of the centre of the wheel nut. That airflow is then used to marshal airflow down the sides of the car to ensure a nice clean flow to the diffuser and rear wing. Not entirely new - Williams and Red Bull have used it before - but the first time it has been so widely adopted.
@CrM: Seems that way, but I wouldn't be surprised if we see some quicker laps this week.
@IceColdBeard™: That's the exact explanation. There are a number of reasons teams do it. One is pit stop practice, which all teams try to load up on at testing, and it also allows the driver to complete practice starts at the end of the pit lane each lap - for obvious reasons they aren't allowed to do that on the grid.
@TheGhoul: I wish drivers would stick to one helmet design, but it seems a bit over the top to create a regulation. Anybody got a favourite helmet design from years gone by? Any good suggestions and I'll trawl through our photo archives to find it.
I just saw a replay of Alonso's first run this morning and the Honda engine filled the garage with white smoke as he left. Most likely burning off some excess oil, but an unusual sight nonetheless.
Alonso has jumped into third on the timing screens with a 1:28.225.
