Still server issues. Now Laura Watkins (head of science policy at STScI) is saying new deadline tomorrow, Oct. 1st at 5pm EDT for all proposers.

There have been over 1,000 JWST proposals submitted in the last 24 hours #JWSTCycle6 (source, submission numbers in my inbox)

I was SO EXCITED for a productive and uninterrupted JWST proposal push. I was traveling for family weddings during the weeks leading up to Cycles 4 and 5, and I was on maternity leave during Cycle 3. Alas, I have been hit with a daycare illness. Cycle 6 was apparently not meant to be either 😩🫠

The 1% student loan interest reduction for enrolling in autopay by Sept 30th is a sham. Me: 2 months for EdFinancial to process payment plan change, still haven't processed my autopay request. Husband: 3 months and Mohela has not processed the payment plan change request, can't enroll in autopay.

I'm being attacked. #JWSTCycle6
Erin's laptop is sitting on her lap, open to the JWST Cycle 6 call for proposals page. Her right hand is on the keyboard and her cat, a long hair tortie, is lying to the side of the laptop and reaching out to attack Erin's hand.

Update, it didn't rain! Between the bounce house and the slushy machine, Ellie and the neighbor kids had a blast 💕❄️🎂
Erin's patio decorated for her daughter's 3rd Birthday. There is a painted sign on the wall with Elsa that says Let it Go! Ellie is 3!. Snowflakes are hanging from the string lights. Balloons and Elsa and Anna cut outs are in the corner, and a bounce house is off to the side in the grass. Erin's daughter sitting on the floor by a pink snowflake cake with a pink "3" candle. She is wearing a sparkly blue Elsa dress and has a snowflake clip in her hair. Her face is covered.

My 3yo was playing with toy ice cream cones this morning and dropped them. She immediately picked up her guitar and wrote a song 😂❤️🎸 (no, really, she did) 🎶🎶 All the ice cream fell down on accident It's all they get It's all they get It's all they get It's no more ice cream cause they melt 🎶🎶

Today I'm on a plane with my 3 yo waiting to taxi and just got a text update that we're delayed 4 hours!? But the flight attendants know nothing. Tbh I might be done with Delta after this year. Two months ago I had a cancelled flight with them, too.

I never confirmed, but I did in fact order the cupcakes. Last week I ordered the decorations. This week's goal is to decide on what food we're having.

Mitigating Charge Migration in JWST NIRISS Reveals That KELT-7 b is a Metal-enriched Ultra-hot Jupiter Orbiting a Young Metal-rich Star
We present the first panchromatic JWST transmission spectrum of an ultra-hot Jupiter, combining NIRISS and NIRSpec observations to constrain KELT-7\,b's atmospheric properties. We show evidence for ch...

We left the gate, and returned to the gate. There is now an issue with the right engine. Look, I don't want to be in the US capital region around July 4th anymore than the next person, but I DO want to go home 😫

No idea WHAT is going on because pilot said someone came on without scanning and we have to restart the boarding process. But a flight attendant says it's about baggage, not us. And CDG is developing departure delays so I fully expect to sit in a takeoff line if we do push from the gate 😫

I switched to health insurance through my husband's work this year because of a medical service I needed that had better coverage on his plan. Just got an email that that benefit is being cut significantly in 60 days. If I switch back in open enrollment, I can't keep my doctor. Are we great yet?

Just a girl taking her cat on an adventure 💕
Erin's daughter is standing in the grass on the right side of the frame facing away from the camera. She is holding Penny's leash. Penny, a tortie cat, is laying in the grass on the left side of the frame, her face turned to the side so we can see it.

Adventure Kitty in training. (JK, it's because she runs out the door any chance she gets and I'm hoping I can train her to go outside with a leash onto the back patio instead of out the front in the direction of the road 🤦‍♀️)
Erin's cat Penny outside on a patio. She is a medium hair tortie that is mostly black with a small amount of orange flecks. Her chin is light brown and her eyes are orange. Her face is turned to the side so we see only her profile. The patio is next to green grass which ends in a wooded area with green trees. She looks nervous, but curious.
